JF-2004 High Voltage Circuit Breaker GIS Partial Discharge Detector

Introduction:

• JF-2004 Circuit Breaker GIS 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 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;
• The humanized man-machine interface facilitates data management of different devices, including traceback of historical data change trends, and 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 a non-intrusive detection method, no power failure during the test, maybe no high voltage source is applied, which is more convenient to use than a traditional pulsed partial discharge detector;
• The test bandwidth range is 30kHz ~ 2.0GHz, suitable for the detection principle of various frequency bands;
