HV HIPOT GDPQ-5000 Power Quality AnalyzerProduct
DescriptionProduct DescriptionGDPQ-5000 Power Quality Analyzer is a
comprehensive test instrument carefully developed by our company
and specially designed for field test of three phases,
multi-functional and intelligent, concise man-machine operation. It
is easy to use, large LCD screen display, high resolution,
interface in both Chinese and English, shock-proof shell structure
and so on. Can simultaneously measure the 4-channel current (ABC
three phase and neutral wire current), 4-channel voltage (ABC
three-phase voltage and neutral line voltage to ground), the peak
value of current voltage, maximum/minimum value over a
period, three-phase imbalance factor, short-time voltage flicker,
transformer K factor, active power, reactive power, apparent power,
power factor and displacement power factor, active power, reactive
power, apparent power, total harmonic distortion and harmonic, etc;
Display real-time waveform, harmonic ratio bar charts of current
voltage; Dynamically capture instantaneous change of voltage
current, monitoring starting current, monitoring the power
parameters and generate the alarm list, generate the trend chart
for a long time record test data.Features2.1. Measurement
functionWaveform real-time display (4 channels voltage/4 channels
current).True RMS values of voltages and currents.The DC components
of voltages.Peak current and voltage values.Minimum and maximum
half-cycle RMS current and voltage values.Phasor diagram
display.Measurement of each harmonic up to order 50.Bar charts show
harmonic ratios of current and voltage of each phase.Total harmonic
distortion (THD).Active, reactive, apparent power, by phase and
cumulative.Active, reactive, apparent energy, by phase and
cumulative.Transformer K factor.Power factors (PF) and displacement
factors (DPF or COSΦ).Short-term voltage flicker (PST).Three phase
unbalance(current and voltage).2.2. Transient capture
functionMonitoring instantaneous change of power grid voltage
current parameters, including the voltage current fluctuations,
voltage current surge, sag and short supply interruption, temporary
overvoltage, impact current and Current voltage instantaneous
distortion. Instruments can store 150 sets of transient waveform at
the same time.2.3. Starting current monitoringMonitoring surge
current of line and the startup current when electrical equipment
is starting, help to correctly design capacity. Can be display the
RMS rising / falling curve In the startup process, the envelope
curve of startup current, waveform of 4 channels current and 4
channels voltage. Recording about 100s after trigger, storage the
current /voltage instantaneous and waveform curve of each cycle in
100s.2.4. Trend chart recording and storing functionStore all the
test parameters of basic test functions (Urms, Uthd, Ucf, Uunb, Hz,
Vrms, Vthd, Vcf, Vunb, PST, Arms, Athd, Acf, Aunb, KF,W, VAR, VA,
PF, COSφ, TANφ),50 voltage harmonics, 50 current harmonics. And
create the trend curve. Record data for a long time according to
need(concurrent selection 20 parameters to record data for once
every five seconds, you can record about 300 days.).2.5. Alarm
functionSet the limit values according to need, monitoring the
values whether overshoot, if overshoot will generate an alarm log,
such as: voltage, current, unbalance, harmonic ratio, frequency,
active power, total harmonic distortion. You can configure 40
different alarms, each group can set different monitoring
parameters (including 50 harmonics, total of 123 different
parameters) and limit values, also can set the shortest time of
overshoot. The log can contain up to 12,800 alarms.2.6. Snapshot
functionAny screen can be saved(screen snapshot), at the same time
automatically records the time and test mode. Such as can save
voltage and current waveform, harmonic bar chart, phasor
diagram etc. It can save a maximum of 60 screen snapshot.2.7.
Communication functionCommunicate with computer via USB, Monitoring
software can display waveform of power quality analysis, read of
the transient waveform, trend chart recording, alarm log,
screenshots, and display on the computer.2.8. Setting functionThe
user can configuration of the time and date, configuration of the
screen contrast and brightness, definition of each phase curve
colours.Choice of type of connection to the network.Configuration
of the type of the current sensors and voltage ratios.2.9. Help
menuEvery stage of operation can press the "help" key to obtain
relevant information. Product ParametersSpecificationsGeneral
