HPPD-300UF Ultrasonic Touch Screen Partial Discharge Detector
General Information
HPPD-300UF is widely used in the partial discharge detection of power systems.
Including high voltage switchgear, ring mains, voltage/current transformer, transformer(include dry type transformer), GIS, overhead lines, cables and other equipment insulation state detection. AE(Ultrasonic) and TEV(Transient Earth Voltage) method is acknowledged and suitable technology to be used in online partial discharge detection.
The following indicators are used to measure the degree of discharge of electrical equipment:
Partial discharge intensity detection: By measuring the discharge signal in a power frequency cycle, the intensity of the 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 cycle, extracts the discharge pulses and characterizes the frequency of partial discharges according to the number of discharge pulses.
Features
With different sensors to achieve partial discharge detection of almost all electrical equipment.
User-friendly man-machine interface facilitates the data management of different devices, including the traceability of historical data change trends, horizontal and vertical data analysis, and realizes a 360° comprehensive diagnosis of the tested device.
Built-in ultrasonic sensor and transient earth voltage (hereinafter referred to as TEV) sensor, also can be connected with external special sensors for transformers, GIS, overhead lines, and cables.
It adopts non-intrusive detection method, no need to power off during the test process, no need to configure additional high voltage source, it is more convenient to use than traditional pulsed partial discharge detector.
The test bandwidth range is 30kHz ~ 2.0GHz, suitable for detection principles of various frequency bands.
