1. Product Overview

Partial discharge is a pulsed discharge that generates a series of physical phenomena and chemical changes, including light, sound, electrical, and mechanical vibrations, both inside and around electrical equipment. These various physical and chemical changes associated with partial discharge can provide detection signals for monitoring the internal insulation condition of electrical equipment. When insulation defects occur within high-voltage electrical equipment, partial discharge signals are typically produced. By detecting and analyzing these partial discharge signals, one can determine if there are insulation hazards within the high-voltage equipment, preventing potential accidents from escalating.

2. Monitoring Principle

Pulse High-Frequency Current Partial Discharge Sensor: The partial discharge process generates a wideband electromagnetic wave. The electrical breakdown process of different types of partial discharges varies, resulting in pulses of different amplitudes and steepness. Consequently, this produces different frequency components of electromagnetic transients and waves. The sensor detects the signal magnitude through a high-frequency coil for data sampling, transmitting the partial discharge signal data to the host for analysis.
