Power quality analyzer designed and manufactured in reference
to GB/T14549-93 Electrical Energy Quality Harmonic Power Quality
Public Utility Grid National Standards IEC 61000-4-31 A Grade
Standards is a special hand-held instrument for testing and
analyzing operation quality of utility grid. It can provide
har. analysis and power quality analysis in electrical operation
for fully monitoring impact upon utility grid during starting
and stopping large-sized electrical equipment. Meanwhile,
it is equipped with a large-capacity memory for long term
data collection testing and PC application software to upload
data onto PC for various analyses.
Functions and Characteristics
Basic Measurement Function:
Functions and Characteristics：
Measure Voltage, current, Freq and record its change
Tren.
Har. Measurement Function:
Measure 3-phase 4-wire (3-volt, 4-current) 1st~50th order
and its THD. Record the change Tren of Har. in a certain order.
Power Measurement Function:
Measure 3-phase active power, apparent power, reactive power,
PF and etc. of 3-phase 4-wire electrical system, and record
change Tren of 3-phase active power.
Characteristics:
1. Small size, light weight and portable
2. High performance Li battery provides long-term power supply
3. Complete 3-phase troubleshooting tools: Measure actual
parameters of each electrical system: Voltage, current, Freq,
power, power consumption (Energy), unbalan. and flicker, har.
and interhar., and catch such events as transient, interruption,
fast Voltage change.

Typical Application:
① Front End Troubleshooting: Utilize screen
to view fast fault diagnostics so as to restore normal
operation of the system
② Predictive Maintenance: Perform testing and prevent
Electrical Energy quality problem before shutdown
③ Service Quality: Check Electrical Energy quality at
service line
④ Long-term Analysis: Test indiscoverable or intermittent
fault
⑤ Load Study: Check the electrical system capacity before
increasing load
⑥ Energy Evaluation: Perform quantized evaluation of
Energy consumption before and after reformation, to
verify effect of low Energy consumption equipment.
