2. Product Introduction
2.1 Notes
The ZXPD-200L partial discharge detector is used for the detection and
evaluation of the insulation status of high-voltage switchgear, ring network
cabinets, transformers, GIS, overhead lines, cable terminals, cable branch
4
boxes and other equipment. There are the following precautions when using this
device:
☀Please use indoors with a temperature of -20 ℃ ～ 50 ℃and a relative
humidity not exceeding 80%;
☀Please stay away from flammable and explosive dangerous goods;
☀Please charge the instrument when it is powered on for the first time, and only
turn on when the charging indicator is on;
☀To prevent interference or leakage, please turn off the power switch when
charging;
☀If the liquid and corrosive substances come into contact with the instrument, it
should be immediately stopped and shut down, and handled by a professional;
☀All connectors are imported connectors, and they should be plugged in and
out. Do not rotate, shake the connector, or pull the cable forcefully. The plug

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.

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;
6
☀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;

3. Operating Instructions
3.1 Structure
ZXPD-200L Host
The front end of the ZXPD-200L host has a built-in non-contact ultrasonic sensor
and a built-in TEV sensor, which can realize the detection of partial discharge of
10
high and low voltage switch cabinets without external sensors. For the detection
of partial discharge of equipment such as cable terminals and cable branch
boxes, it is only necessary to connect the corresponding special sensor through
the sensor expansion port at the bottom of the host. The host can automatically
switch the measurement mode according to the different sensors. For sensors
that can be connected to ZXPD-200L, please refer to the optional part in Table 1
of the product configuration list.
3.2 System power on and off and status display
Power button
ZXPD-200L realizes the switch on and off by touch switch, only need to touch on
the power label, the status indicator will show the current working status of the
host after power on, if the power adapter is connected, and the indicator C Lights
up until the battery is fully charged.
The indicator S is used to show the status of data sampling or online status. In
normal measurement mode, the S status indicator flashes red, and when the
host is online (connected with PC) and the PC is successfully connected, the S
status indicator flashes green .
