xceeding the rated maximum to the input terminals.

e

• Do not short-circuit two wires to be measured by bringing the voltage cord clip

current sensor into contact with them. Arcs or such grave accidents are

or
likely to occur.

• To prevent a short-circuit or electric shock, do not touch the metal part of the

onnecting voltage cord tip.

c

• To prevent electrical shock and personnel injury, do not touch any input termi­nals on the VT (PT), CT or the instrument when they are in operation.

Connect measurement lines to Model L1000 Voltage Cord securely. If a terminal
is loose, the contact resistance will increase, resulting in overheating, equipment
burnout, or a fire.

When the instrument's power is turned off, do not apply voltage to the instrument.
Doing so may damage the instrument.

While Measuring

If an abnormality such as smoke, strange sound or offensive smell occurs, stop
measuring immediately, disconnect from the measurement lines, turn off the
instrument, unplug the power cord from the outlet, and undo any changes to the
wiring. Contact your authorized Hioki distributor or reseller as soon as possible.
Continuing to use the instrument may result in fire or electric shock.

Overview Chapter 1

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

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, transformer 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 cause?

(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 pinpoint 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 distortion, transient voltages, high-order har­monics [noise at frequencies of several kHz and above])

• Current abnormalities (leak current, inrush current)

Step 2: Identifying the malfunctioning component (measurement location)

Check the following:

HIOKI PQ3198A961-03

1.1 Procedure for Investigating Power Supply Quality

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
power supplies, principal electrical system operating cycle, additions or changes to facility equipment,
facility distribution circuitry)

Step 4: Making measurements with the power supply quality analyzer

Measurements are performed using the following procedure:

1. Perform quick setup and adjust the relevant settings.

• Connect the measurement line and select the quick setup
instrument to identify a power supply malfunction whose cause is unknown, it is recommended to
select the voltage abnormality detection pattern.)

• Verify that the proper connection has been selected on the [SYSTEM]
have been configured appropriately (nominal input voltage, frequency, range, interval time, etc.). Verify
that events are not being generated too frequently.

• If, based on the information obtained in Steps 2 and 3 above, you find that some necessary settings have
not be

en configured by the quick setup process, reconfigure them on the [SYSTEM] screen.

• Check instantaneous values (voltage level, voltage
distortion [THD]) on the [VIEW] screen.

2. Start recording.

• Press the ST

• Check the event detection state on the [EVENT] sc
the settings or thresholds. (If too many events are occurring, you can increase the thresholds based on
measurement results.)

• Continue recording for the necessary period, check th
the detected events, and take corrective action as appropriate. (The PQ3198 can be used not only for
the investigation phase, but also to verify the effectiveness of corrective action taken.)

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.

If current consumption in a building is high while the voltage is low, the cause likely lies inside the build­ing. If the voltage and current are both low, the cause is likely
important to select the right measurement locations and to measure current.

 Check power trends.

Overloaded equipment can cause problems. By understanding power trends, you can more easily iden­tify problematic equipment and locations.

 Check when the problem occurs.

Equipment that is operating or turning off or on when abnormalities (events) are recorded may be prob­lematic. By understanding the precise times at which a

 Check for heat and unusual sounds.

Motors, transformers, and wiring may produce heat or unusual sounds due to causes such as overload­ing or harmonics.

19

 Record abnormal waveforms
 Record voltage fluctuations
 Observe power supply waveforms
 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 circuit 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 measurement band, it should
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

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.

To 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 secondary is shorted, high current
flow in the secondary could burn it out and cause a fire.

• When using an external CT, avoid open-circuiting the secondary winding. If

urrent 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 can cause power measurement 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

rounded.

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.
