Handling the cords and current sensors
Use only the Hioki specified voltage cords and input cables. Using a non-specified cable may
result in incorrect measurements due to poor connection or other reasons.
Important
If the insulation on a cord melts, the metal conductor may be exposed. Do not
use any cord whose metal conductor is exposed. Doing so could result in an
electric shock, burn, or other hazards.
To prevent an electric shock, do not exceed the every rating shown on either the
instrument or the options for voltage measurement, whichever is worse.
• The cable is hardened in freezing temperatures. Do not bend or pull it to avoid tearing
its shield or cutting cable.

To assess power supply quality (power quality)
(There is no known problem with the power supply, and you simply wish to assess its quality.)
• Periodic power supply quality statistical investigations
• Testing after the installation of electric or electronic equipment
• Load investigation
• Preventive maintenance

1.1 Procedure for Investigating Power Supply
Quality
By measuring power supply quality parameters, you can assess the power supply's quality and
identify the causes of various power supply malfunctions. The PQ3198's ability to measure all
power supply quality parameters simultaneously makes this process a quick and simple one.
This chapter describes the power supply quality investigation process.
Step 1: Identifying a clear objective
Chapter 1 Overview
Find Quality Products Online at: sales@GlobalTestSupply.com
www.GlobalTestSupply.com
16
Where is the issue occurring?
• Principal electrical system
(Large copier, uninterruptible power supply , elevator, air compressor, air conditioning compressor, battery
charger, cooling system, air handler, time-controlled lighting, variable-speed drive, etc.)
• Electric distribution system
(Conduit [electrical conduit] damage or corrosion, tr ansformer heating or noise, oil leak, circuit breaker
operation or overheating)
1
When does the issue occur?
• Does it occur continuously, regularly, or intermittently?
• Does it occur at a specific time of day or on a specific day?
2
What type of investigation (measurement) should be performed to find the ca use?
(It is recommended to measure voltage, current, and possibly power continuously. By analyzing voltage and
current trends when the issue occurs, it will be easier to pinpoi nt the cause of the problem. Additionally,
simultaneously measuring multiple locations is an effective way to quickly identify the cause.)
• Electrical substation internal lines (power companies only)
• High or low voltage at a service line entrance
• Distribution boards and switchboards
• Outlets and other points of power supply for electric and electronic equipment
3
What is the expected cause?
• Voltage abnormalities (RMS value fluctuations, waveform distorti on, transient voltages, high-order harmonics [noise at frequencies of several kHz and above])
• Current abnormalities (leak current, inrush current)

Step 3: Checking investigation (measurement) locations (collecting site data)
Collect information (site data) from as many locations as possible to prepare for the investigation. Check
the following:
1. Connection (1P2W/1P3W/3P3W2M/3P3W3M/3P4W/3P4W2.5E)
2. Nominal input voltage (100 V to 600 V)
3. Frequency (50 Hz/60 Hz)
4. Need for neutral wire measurement and DC voltage measurement
5. Current capacity (necessary in order to select current sensor to use for measurement)
6. Other items related to the facility as a whole (c
power supplies, principal electrical system operating cycle, additions or changes to facility equipment,
facility distribution circuitry)

1.1 Procedure for Investigating Power Supply Quality
Advice for identifying the cause of abnormalities
Record voltage and current trends at the power circuit inlet.

Measure harmonics
Measure flicker
Measure power
One instrument does it all!
How does the PQ3198 record abnormal waveforms?
The instrument automatically judges and records a range of problems.
Transient voltages
Transient voltages are caused by lightning strikes, circuit-breaker and relay
contact obstructions and tripping, and other phenomena. They are often characterized by precipitous voltage variations and a high peak voltage.
Flicker (ΔV10, IEC)
Flicker is caused by blast furnace, arc welding, and thyristor control loads. The
resulting voltage fluctuations cause flicker in light bulbs and similar phenomena.
Voltage dips (falling voltage)
Short-lived voltage drops are caused by the occurrence of a inrush current with
a large load, such as when a motor starts.
Interruptions
In an interruption, the supply of power stops momentarily or for a short or long
period of time due to factors such as a circu it breaker tripping as a result of a
power company accident or power supply short-circuit.
Voltage swells (rising voltage)
In a voltage swell, the voltage rises momentarily due to a lightning strike or the
switching of a high-load power line.
Harmonic and high-order harmonic elements
Harmonics are caused by distortions in the voltage and current caused by the
semiconductor control devices that are frequently used in equipment power
supplies.

: It is recommended to use the PW6001 or PW3390 for high-precision measurement. Although this instrument may
yield different voltage readings than the PW6001 and PW3390 due to differences in measureme nt band, it shoul d
yield approximately the same current and power values as the PW6001 and PW3390 since current waveforms
approach the fundamental wave. It can also be used to measure the efficiency of DC/3-phase inverters.

3.7 Connecting the Current Sensors
Be sure to read the "Usage Notes" (p.7) before connecting current sensors.
Plug the current sensor cables into the current input jacks on the instrument (the number of connections
depends on the lines to be measured and selected wiring mode). See the instruction manual supplied
with the current sensor for specification details and usage procedures.
T o prevent an electrical shock and bodily injury, do not touch any input terminals
on the VT (PT), CT or the instrument when they are in operation.
• When using an external VT (PT), avoid short-circuiting the secondary winding.
If voltage is applied to the primary when the seco ndar y is sho rte d, high curr ent
flow in the secondary could burn it out and cause a fire.
• When using an external CT, avoid open-circuiting the secondary winding. If
urre
nt flows through the primary when the secondary is open, high voltage
c
across the secondary could present a dangerous hazard.
• Phase difference in an external VT (PT) or CT ca n cause power measure ment errors.
For optimum power measurement accuracy, use a VT (PT) or CT that exhibits mini
mal phase difference at the operating frequency.
• To ensure safety when using a VT (PT) or CT, one side of the secondary should be

unded.

4.9 Using the Instrument during a Power Outage
If the supply of power to the instrument is interrupted (for example, during a power outage), it will operate
using battery power (a fully charged battery provides enough power to operate for about 180 minutes).
However, the instrument will turn off about 180 minutes after the outage occurs . Once the power is back
on, the instrument will turn back on and resume recording. Integral values and other data will be reset,
and the integration process will resume.
