Overview
This system is a widely used partial discharge testing instrument for power utilities, manufacturers and research institutes. It is suitable for measuring partial discharge in high-voltage electrical equipment such as transformers, instrument transformers, HV switches, ZnO surge arresters, and power cables. It supports type tests, insulation condition monitoring, and operational supervision. The system includes an intelligent control console, isolation filter, partial discharge-free test transformer, partial discharge detector, coupling capacitor, protective resistor, and calibration pulse generator.
