8. Power Quality Measurement:

The instrument measures the three power quality events, namely voltage sag, voltage swell and overcurrent.

These events get stored in tabular form giving the corresponding date & time of event start and its duration. The minimum event duration that can be recorded is 100mseconds.

Maximum of 30 such events get stored in the table one by one in the first in first out manner i.e., the 31st event replaces 1st event and so on. Touching a particular event in the table gives the detailed information about the corresponding event. Consider an example for SAG detection:

“Ëvent’s Start” indicates the phase which had the minimum value during the Event’s start and “Ëvent’s End” indicates the phase which had the minimum value during the Event’s end.

In case of swell/ overcurrent event, MAX would appear in place of MIN and respective phase readings would be taken considering the maximum values (instead of minimum values taken in case of sag).

The Threshold and Hysteresis settings (Section 3.2.6) done in % by the user results in the following values: (Consider Figure 9.1)

Figure 9.1: Waveform of SAG detection for 1P2W system

Note: (1) For the events to be detected, it is recommended to bring the system voltage and current for all channels to their corresponding nominal values. (2) The nominal voltage is the L-L PT Primary value in case of 3P3W system and L-N PT Primary value in case of 3P4W and 1P2W system. (3) The nominal current is taken to be CT Primary value. (4) In case of polyphase systems, sag begins when the voltage of one or more channels falls below the threshold and ends when the voltage on all measured channels is above the threshold plus the hysteresis voltage (Figure 9.1). Similarly, the Swell/ Overcurrent event is shown in Figure 9.2.

Example for sag:

Nominal voltage = 100V Threshold = 80% = 80V Hysteresis = 2% = 2V

9.1 Pulse Output :

Pulse output is the potential free, very fast acting relay contact which can be used to drive an external mechanical counter for energy measurement. This pulse output can be congured to any of the following parameter through instrument’s setup parameter screen

1) Active Energy (Import) 2) Active Energy (Export)

3)Reactive Energy (Import) 4)Reactive Energy (Export)

5)Apparent Energy

This instrument is provided with either 1 or 2 relay for pulse output as well as for limit switch

Pulse duration 60 ms, 100 ms or 200 ms **No. of Pulses per Ampere hour = Maximum Pulses / CT Ratio Where, CT Ratio = (CT primary/ CT Secondary)

9.2 Limit Switch :

Limit switch can be used to monitor the measured parameter (refer TABLE 2) in relation to a set limit. The limit switch can be congured in one of the four mode given below:-

1) Hi alarm & Relay Energized Relay.

2) Hi alarm & De-Energized Relay.

3) Lo alarm & Energized Relay.

4) Lo alarm & De-Energized Relay. Limit switch has user selectable Trip point, Hysteresis, Energizing Delay & De-Energizing delay.

54

Hi Alarm:

If Hi-Alarm Energized or Hi Alarm De-Energized option is selected then relay will get energized or Deenergized, if selected parameter is greater than or equal to trip point.

Lo Alarm:

If Lo-Alarm Energized or Lo Alarm De-Energized option is selected then relay will get energized or Deenergized, if selected parameter is less than or equal to trip point.

# Note: For Lo-Alarm configuration, set the values of trip point & hysteresis such that %

trip point + % hysteresis should be less than 100% Value.

Example for Phase angle:

If trip point is set 70% then maximum applicable hysteresis is 42.8%. i.e Trip point 70% (252 ) + Hysteresis 42.8% (107.8 ) = 359.8 If total value is greater than the 100% i.e. ° ° ° 360° then relay will not release.

Note: This function will work irrespective of +/sign. It depends only on value.

Trip point can be set in the range as specified in TABLE 3 of nominal value for Hi-Alarm & 10% to 100 % of

nominal value for Lo-Alarm.

Trip point:

Example for PF:

For Hi-Alarm Energized, if trip point is 70% & hysterisis is 30%, then trip value = 0 . 7 x 9 0 ° = 6 3 ° . T r i p p i n g P F = cos(63)=0.4539 & hysterisis = 0.3 x 0.4539 = 0.136.

Hence, the relay will energize above 0.4539 and deenergize below 0.3179.

Hysteresis can be set in the range of 0.5% to 50 % of set trip point. If Hi-alarm Energized or Hi-alarm Deenergized is selected then relay will get De-energized or Energized respectively, if set parameter value is less than Hysteresis. Similarly if Lo-alarm Energized or Lo-alarm De-Energized.

Note : In case of lo alarm if trip point is set greater than 80% then the maximum hysteresis can be set such that the total Trip point+ Hysteresis(% of trip point value) will not exceed 120% of range. For example :If trip point is set at 90%, then maximum 33.3% hysteresis should be set such that, [90 + 29.99 (33.3% of 90)] = 120.

Hysteresis:

Hysterisis point

Energizing Delay:

The energizing delay can be set in the range from 1 to 9999 seconds.

De-Energizing Delay:

The De-energizing delay can be set in the range from 1 to 9999 seconds.

11. Installation

Mounting is by four side clamps, slide the side clamps through side slot till side clamp gets rmly locked in a groove (Refer g.) Consideration should be given to the space required behind the instrument to allow for bends in the connection cables. As the front of the enclosure conforms to IP54 it is protected from water spray from all directions, additional protection to the panel may be obtained by the use of an optional panel gasket. The terminals at the rear of the product should be protected from liquids. The instrument should be mounted in a reasonably stable ambient temperature and where the operating temperature is within the range -20 to 70 C.

2. Voltages dangerous to human life are present at some of the terminal connections of this unit. Ensure that all supplies are de-energised before attempting any connection or disconnection.

3. These products do not have internal fuses therefore external fuses must be used to ensure safety under fault conditions.

0

Vibration should be kept to a minimum and the product should not be mounted where it will be subjected to excessive direct sunlight.

61

11.1 EMC Installation Requirements

This product has been designed to meet the certication of the EU directives when installed to a good code of practice for EMC in industrial environments, e.g.

1.

Screened output and low signal input leads or have provision for tting RF suppression components, such as ferrite absorbers, line lters etc., in the event that RF elds cause problems.

Note: It is good practice to install sensitive electronic instruments that are performing critical functions, in EMC enclosures that protect against electrical interference which could cause a disturbance in function.

2.

Avoid routing leads alongside cables and products that are, or could be, a source of interference.

4. ESD precautions must be taken at all times when handling this product.

3.

To protect the product against permanent damage, surge transients must be limited to 2kV pk. It is good EMC practice to suppress differential surges to 2kV at the source. The unit has been designed to automatically recover in the event of a high level of transients. In extreme circumstances it may be necessary to temporarily disconnect the auxiliary supply for a period of greater than 5 seconds to restore correct operation. The Current inputs of these products are designed for connection in to systems via Current Transformers only, where one side is grounded.

11.4 Auxiliary Supply

The should ideally be powered from a dedicated supply, however it may be instrument powered from the signal source, provided the source remains within the limits of the chosen auxiliary voltage.

11.5 Fusing

It is recommended that all voltage lines are tted with 1 amp HRC fuses.

11.6 Earth/Ground Connections

For safety reasons, CT secondary connections should be grounded in accordance with local regulations.
