Darui Electric recommends for you:
Test transformer, partial discharge detector, will generate electromagnetic waves, which when propagating outward will generate a transient voltage signal to ground. The magnitude of this signal is directly related to the intensity of the partial discharge and the distance to the discharge point. A dedicated detector can be used for detection, and this detector is the partial discharge detector.

Product aliases:
Partial discharge detector, partial discharge tester, PD detector, partial discharge test system
Performance features:
1. The partial discharge detector has the characteristics of high detection sensitivity, wide applicability to test objects, and high signal-to-noise ratio.
2. It adopts a large-screen oscilloscope tube, with clear display of test waveforms, high-frequency elliptical scanning (power consumption less than 1 volt-ampere), large dynamic range of the amplification system, multiple frequency band combinations (nine types), auxiliary zero-marking system, linear and logarithmic dual-function pointer meters and digital meters, which can simultaneously display the discharge amount of discharge pulses.
3. The partial discharge detector is a powerful auxiliary tool for researching and developing new high-voltage electrical products and improving product quality, and it is also an effective testing instrument for on-site judgment of whether equipment is normal.
4. The partial discharge detector is used in conjunction with the calibration pulse generator, especially suitable for power departments, manufacturers, and scientific research units
