There are two PF set-points to be set in TPF-56/16. The UPPER limit and
the LOWER limit. TPF-56 ensures that PF-UPPER is never exceeded.
Additionally, “No change band” to minimum KVAR band size equal to
smallest bank KVAR x 1.5 ensures no hunting during the low KW loading.
TPF-56 is normally set for PF settings as per first two diagrams shown
where PFLOWER is inductive. This philosophy helps to optimize the
system maximum KVAR to be used as well as reduces the number of
switching operations during higher loading conditions. This ensures better
life expectancies of the switched capacitors as well as the switching
devices.
This methodology of KVAR compensation reduces the complex settings
that are used by conventional PF relays. The settings like C/K ratio and
KVAR offsets/shifts are eliminated which makes TPF-56 user friendly and
thus easy to commission.
For all the three conditions shown in the above diagrams, 4-quadrant
operation is achieved. Typical example of 4-quadrant operation is “CoGeneration Plants” and “Wind-Power Generation”. But with most
conventional consumer applications, only +Ve KW is seen, where the
Auto Synchronization feature can be used.

Total number of banks that are operational are 16.
Bank no. 1 is declared as fixed and is in ON condition.
Bank no. 2 is in ON condition.
Bank no. 3 is declared as faulty.
Bank no. 4 is in discharging state.
Bank no. 5 to 16 are in OFF condition.
“I AM OK”, flashing Green LED indicates the controller health status.
This LED is located at the extreme, left-hand, bottom side of the front
panel, as viewed by the user.
This LED, if continuously ON or continuously OFF, indicates
malfunctioning of the controller.
On powering up the unit, there is power-on discharge time given
for the capacitors to discharge completely. However, if the user is sure
that the capacitors are discharged, then on pressing the left key would
allow the controller to come out of the discharge time and thus user
need not wait for the discharge time to get complete and thus saves
time.

In manual mode the user can manually turn ON/OFF the banks. But
this is not allowable for all the faults. In case of the following faults,
turning ON the banks in manual mode is NOT allowed:
1] Under Voltage (UV)
2] Over Voltage (OV)
3] Under Frequency (UF)
4] Over Frequency (OF)
Entry in to Manual Mode of operation first turns-off all the Capacitor
Banks.
This mode is normally used to perform the operations like:
• Resetting of faulty banks to healthy status.
• Checking the Capacitor banks by turning them ON/OFF.
• Declaring specific bank/banks faulty. Masking of the banks so that once
auto mode is selected, these faulty declared banks would not be used for
PF correction.
For Declaring banks faulty or Resetting faulty banks:
While in Manual Mode default screen, press ENTER key.
The cursor above bank 1 will start blinking. Use keys to select the
specific bank. Then use key to declare it faulty.
To reset the faulty bank, bring the blinking cursor to that bank and use
key again to declare that bank as healthy.

For over-voltage and under-voltage fault, the option
available is as hereunder:
1=Fast Off Step
For all the faults, normally two limits are defined. One is
Detection Limit and another Resume Limit. Detection
Limit if exceeded (above/below) by the parameter would
mean the action as defined by parameter in type of fault
(as given here-above). Resume Limit defines the
parameter value above/below which the fault is
deactivated.
• Over-Voltage: As name suggests, its for Over-Voltage
conditions persisting in any one phase for 3 sec.
• Under-Voltage: For Under-Voltage conditions in any one
phase persisting for 3 sec.
• Under Load fault: The values here are set as % of
Maximum rated kW. This is useful in case of banks are put
in circuit to take care of no load compensation. Value for
this Under-Load KW can be calculated as shown here.
•Over current: The TPF-56 detects if the supply system is
overloaded, then it is for warning indication. No capacitor
banks are switched off with this detection.
•Temperature fault: As the name suggests, it displays the
over temperature fault if the temperature exceeds the set
limits. There are two parameters related to it, i.e. the
temperature upper limit and lower limit. If fault is set,
then “Fast Off step” action is undertaken.

•Out of Banks Fault: This is only with Disable and
Enable options. If Enabled, then unit will indicate the
out of bank fault if for two consecutive correction
cycles, PF is more inductive than Lower PF set point
and all the healthy capacitor banks are in ON state.
In short, the total Capacitive KVAr is less that the
required, to maintain PF within the limits set.
Harmonic Overload: This has two options, namely
Disable and Fast Off.
This is basically to indicate the harmonic faults.
•V-THD Threshold limit (%):. If percentage of voltage
THD is above the set limit, then voltage harmonics
fault (VH) will be displayed on the default screen.
Average THD in any one phase over 3 min period if
exceeded, then this fault is activated.
The VTHD limit can be set through V-THD threshold
limit screen.
•I-THD Threshold limit (%):If percentage of current
THD is above the set limit, then current harmonics
fault (IH) will be displayed on the default screen.
Average THD in any one phase over 3 min period if
exceeded, then this fault is activated. The I-THD limit
can be set through I-THD threshold limit screen.
•Harmonic Flt Auto-Rst: This fault has two options,
namely Enable and Disable. If it is enabled and
Harmonics exceeds from the set limits then
controller switch OFF all the capacitor bank steps
until harmonics come down within set limits. After
harmonics comes below the set limits controller
clears the fault automatically after a period of 180
seconds & is ready to switch ON the capacitor bank
steps. and if disable controller shows the fault until
you reset the fault manually.
•Harmonic Lmt Ext Loading: User can set the actual
load limit in percentage of rated load here for which
harmonic fault can be detected.
•Low Rng Mul Fact For VTHD: By setting this factor
user can extend the VTHD fault limit.
•Low Rng Mul Fact For ITHD: By setting this factor
user can extend the ITHD fault limit.
•Bank Health tolerance: In the capacitor bank health
check monitoring, this indicates the tolerance
between the user set bank kVAr values and the
actual kVAr as calculated by the controller.

two bank execution. User can set it as instantaneous or 1
Sec as a option.
•Fixed bank setting: In this, any bank(no of banks
depends upon the steps connected) can be set as fixed
bank.
•Unequal Bank kVAr [1….16]: The capacitor bank step
configuration values are to be set here .These parameters
are to be defined for each bank kVAr (at defined
Capacitor Bank Voltage). TPF-56 has an in-built intelligent
algorithm to select the best possible combination to suit
the exact kVAr requirement for compensation.

Notes on Protection and Functionalities:
(1)If current CT connections are not connected to the TPF-56 unit i.e.
if no current is detected or the detected current is below 1.5% of
rated load current, then, TPF-56 would show the following display
on the LCD.
(2) If Harmonics overload fault is enabled, and if the voltage or current
THD exceeds the set limit, then TPF-56 would show the following
display on the LCD.
Pressing the Enter key, would reset the VH/IH fault even if
voltage/current THD is above the set limit. The fault indication would
continue till the respective THD is above the set limit. In case of THD
above limit, all capacitor banks are switched off to protect them.
TPF – 56 also have a parameter called Harmonic Fault Auto-
Reset. If enabled, then the controller automatically clears off the
harmonic fault after 180 seconds when the harmonic level falls
down below the Set limits
(3) Battery Low :If the internal Lithium coin Battery Voltage of nominal
3 V drops below 2.6 V then the controller will flash “Battery Low!!!”
message on the Default screen display (in a blinking state with certain
delay) until the battery is replaced by a new healthy battery. Please
note that even when the “Battery Low!!!” message is being flashed on
the LCD display the user can still operate the keypad.
It is essential to have the battery operational to maintain the Real
Time Clock and Calendar information. If the Battery Voltage falls
below certain limit, the RTCC will stop functioning. All Data Logging
operations are prohibited if the RTCC is Stopped.

(4)Battery Replacement: The RTCC Battery is Maxell Make, CR2032 type.
This can be replaced without opening the Controller through the Slot
provided on the Top Left-Hand side of the Controller.
The Old Battery should be removed using insulated tip plier and a new
Battery is to be placed using the same insulated tip plier.
Please observe the correct positive and negative polarity of the Battery
while replacing.
The positive of the Battery should be towards the viewer (LCD Side) and
the negative towards the PCB. It is always recommended to replace this
battery with Auxiliary supply to the Unit in ON condition. This would
prevent re-setting up of RTCC date. Still if one wishes, it can be safely
done with unit in Power down condition too without fear of loosing data.
Note: Unit is equipped with EWPF logic. With Battery Faulty condition or
Battery Low condition, Battery Replacement can be safely done without
data download and without a fear of loosing any logged data or Energy
Counter values or Capacitor bank logged kVAr values. Such battery
replacement can be even safely be done with unit in power down
condition.

Intelligent Power Factor Controller TPF-56
Events and interval based data-logging facilities:
The TPF-56 has non-volatile memory where internal operational status is
monitored and change of state, called as an “Event”, is internally recorded in
the non-volatile memory, with RTCC date & time stamping for the event data.
Up to 1024 latest events are held in the memory which can be off-loaded
from the controller to a PC or to a hand-held unit (HHU) for further analysis.
This information is useful to the user because the user comes to know when
a particular fault occurred and when the controller resumed from the faulty
condition.
The “Data View” Application Software for PC, is provided to the users of
TPF-56 Unit to download and process the data directly from the TPF-56 using
a laptop/PC or download from Hand Held Unit(HHU), if the HHU already has
the data from TPF-56. A separate User Manual is available for the “Data View”
Software.
“Data View” is for not only for data downloading from the TPF-56 Units, but
also for presenting the captured information in a User-Friendly manner.
TPF-56 Unit is capable of internally logging various important Electrical
Parameters as well as the Capacitor Bank Status, on a fixed Time Interval
Basis.
The most common Time Interval provided is that of 1 Hour, therefore the
data-logging is on an Hourly basis.
Thus, the Hourly logged records in the TPF-56 Unit are first downloaded by
“Data View”, and then, analysed and presented to the User in various ways.
“Data View” is capable of generating the reports in visual forms as well as in
print form for hard-copy storage.
The Non-Volatile Memory of the TPF-56 Unit is capable of logging the Hourly
Data for a maximum duration of 124 days. The “Data View” downloads all
logged data of 124 days. Selecting shorter time interval period for logging will
correspondingly reduce the number of days for the logged data because the
amount (size) of memory for data-logging, is internally fixed in the design.
“Data View” has the ability to show the date of downloading and expected
date of next download. Time span between date of downloading and next date
of downloading is 90 days.
This facility allows about One Month margin to get the data from the field.
This is important so that one actually does not miss any field data.
If the logged-data is not off-loaded from the Controller in time, the old data
will be over-written by the Controller to always present the latest data.

Page 42
For the maintenance purpose, it is possible to generate “faults” related
information for a particular date and time. It also possible to see the Status
of the Capacitor Banks of TPF-56 Unit, at a specified date and time.
Please refer page no. 20 of this user manual for the connection
diagram between PC and the TPF-56 Unit.
Aux. Input AC Power “Early Warning Power-failed”
monitoring (EWPF):
The TPF-56 has the ability to detect the “power-failing” condition by way of an
internal “Early-Warning” of impending AC Input Aux. Power Failure, and takes
preventive measures for the following:
In case of “power-failing” Early-Warning condition, the TPF-56 saves all the
dynamic parameters in its non-volatile memory (EEPROM) along with RTCC
current date and time. So, the “Power-Down” event is precisely known.
Similar Record is created at the time of AC Aux. Input Power-Up. This enables
the PC Side Data-View / Data View Software to find the interval for which the
TPF-56 did not receive Power Supply.
After “saving” in to non-volatile memory operation, the LCD back-light
which was off at the detection of “Power-Failing”, it flashes on once which
indicates that the memory saving operation has been successfully carried-out
by the TPF-56 Unit.
“Early warning Power Failed” additionally has one critical functionality for
taking care of critical value storage in EEPROM. This prevents any data loss in
Interval or Events records or Energy Counters or Capacitor kVAr values to be
lost in case of Battery Fault or Replacement of Battery even with Power Down
condition.

Before panel is powered up for the first time
1. Panel Wiring Check
Ensure that all connections in the panel are tightened properly and there are
no loose connections. Also ensure that the wiring is done as per the wiring
diagram. Keep wires of high-voltages and low-voltages, such as CT
feedbacks, separate from each others, to avoid cross-coupling or induced
signals. The Unit should be firmly mounted in the panel using the 4
mounting clips/clamps at the back.
2. Power Wiring Check
Ensure that the power cables are connected properly from the Panel I/C to
the feeder I/C or the transformer bushings. The connection has to be after
the Load Feed back CT, looking from the Transformer side.
Ensure that the Bus Bars and/or Lugs are clean and free of Dust, Corrosion
or Oxidation on the contact sides so that good electrical connection is
maintained. The surface area should be flat so as to get maximum contact
area.
If required, Clean the Bus Bars and/ or Lugs by rubbing it with Polish Paper
to remove the oxidation layer. Provide contact paste in between the contacts
surfaces.
Not performing this can result in to a weaker source point for Capacitor
charging during Step on and this can generate undesirable Noise which can
hamper the performance of equipments installed in the capacitor panel.
3. Load Current Feedback CTs connections
Ensure that the load current feedback CTs connections are done properly.
Confirm that correct phase CT is connected with the correct phase input
terminals.
CT connections MUST be done carefully, so as to ensure that the wire do not
get opened and there is no loose contacts or loose connections.
Loose connection or open CT secondary will result in very high voltages
getting developed at the CT Connection Terminals which will damage the CT
and also damage the TPF-56 Unit as well.
Commissioning Instructions

After panel is powered up
1. Remove the fuses/switch-off MCBs/MCCBs which are in series with every
capacitor bank. Connect supply to the TPF-56 Unit. Keep the load
current feedback in shorted condition.
2. Turn ON the supply to the panel and set Date/time & various other
parameters as per the panel configuration. It is important to understand
the meaning of every parameter from the instructions given before and
then put the appropriate values in them. Wrong values entered can give
the wrong performance of the panel.
3. Once the parameterization is complete, put the TPF-56 Unit in Manual
mode to check every bank command is transmitted to the Thyristor
switch . This can be observed by turning ON the Thyristor Switch supply
MCB on. The corresponding output should be checked for physical turn
ON / OFF of the Thyristor Switch.
4. Once all the Thyristor switches are seen to be getting the correct
commands, switch off the supply to the panel and replace all the fuses
(or turn on MCBs/MCCBs if they are provided instead of fuses). Turn on
the panel.
5. Put TPF-56 back in Manual mode and turn ON/OFF the individual steps.
Use Tong tester (ac current measurement) to check that current in all
three phase of the corresponding bank are OK. In case any bank is not
showing the desired current, check for capacitor bank healthiness or
power circuits.
6. Keep all the banks in off mode. Remove the shorting of Load Current
feedback CTs. In case kW value is seen as –Ve for any phase, CT is with
wrong polarity.
7.Manual synchronization is mandatory by physically checking the CT
connections and polarity.
Observe panel performance for about 2 Hours after commissioning.
