Portable GIS Partial Discharge Test System With PRPD Capablity For
Fied Use
Brief description:
The ZXPD-200L partial discharge detector can be widely used in the
theater detection of power systems, including the insulation status
of high-voltage switchgears, ring network cabinets, voltage /
current transformers, transformers (including dry-type
transformers), GIS, overhead lines, and cables Detection, to
measure the discharge level of electrical equipment through the
following indicators:
Partial discharge intensity detection: By measuring the discharge
signal within a power frequency period, the intensity of partial
discharge is characterized according to the maximum value (dB) in
the discharge pulse sequence.
Partial discharge frequency detection: The device measures the
discharge signal within a power frequency period, extracts
discharge pulses and characterizes the frequency of partial
discharges according to the number of discharge pulses.
Features:
☀ Configure different sensors to realize partial discharge
detection of almost all electrical equipment;
☀ Provide time domain waveform, PRPD, PRPS and other discharge
patterns to realize the analysis of different discharge types;
☀ Humanized man-machine interface facilitates data management of
different devices, including traceback of historical data change
trends, horizontal and vertical data analysis, and realizes 360 °
comprehensive diagnosis of the device under test;
☀ Built-in ultrasonic sensors and transient ground voltage
(hereinafter referred to as TEV) sensors, which can be connected
with special sensors such as transformers, GIS, overhead lines and
cables;
☀ Adopt non-intrusive detection method, no power failure during the
test, maybe no high voltage source is applied, which is more
convenient to use than traditional pulsed partial discharge
detector;
☀ The test bandwidth range is 30kHz ~ 2.0GHz, suitable for the
detection principle of various frequency bands;
