Two-in-One Partial Discharge Sensor

Model:
HMJ1010-AT

Product Overview:
The intelligent Two-in-One Partial Discharge Sensor integrates Ultrasonic (AA) and Transient Earth Voltage (TEV) detection technologies. It is widely used in substations, switching stations, and other power facilities for monitoring partial discharges in ring main units (RMUs), switchgears, and similar equipment. The sensor helps detect potential insulation defects early, ensuring the safety and reliability of power systems.

Key Features:

1、Multi-Parameter Detection:

Combines TEV and AA detection methods to capture both electrical and mechanical vibration signals of partial discharge. Through comprehensive multi-dimensional data analysis, it provides accurate assessments of insulation conditions and partial discharge severity.

2、Strong Anti-Interference Capability:

Designed with advanced filtering and shielding techniques to effectively suppress electromagnetic interference and noise. This ensures stable and reliable performance in complex power system environments.

3、Smart Diagnosis & Early Warning:

Equipped with intelligent algorithms and data analysis modules, the sensor processes large amounts of real-time data to automatically identify partial discharge characteristics and patterns. It performs fault diagnosis and issues early warnings based on preset thresholds and rules, helping prevent insulation failures.

4、Easy Installation:

The sensor supports magnetic or other easy-to-install mounting methods, allowing on-site installation and maintenance without powering down the equipment. This ensures non-invasive deployment and does not affect the normal operation or power supply of the grid.
