JF-2004 Partial Discharge Detect Transmission Line Test
Equipment Introduction:- JF-2004 Partial Discharge Detect Transmission Line Test Equipment 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 boxes and other
equipment.
- 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.
Standards:- ASTM: ASTM D2863
- ISO: ISO 4589-2
- NES: NES 714
Application Field:- Building Materials;
- Wire&cable;
- Upholstered furniture;
- Others;
Features:- Configure different sensors to realize partial discharge detection
of almost all electrical equipment;
- 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;
