Product Description
Measurement Range | Transient Earth Voltage (TEV): 0 - 60 dBmV; Ultrasonic (AA): 0 - 60 dBµV; |
Transient Earth Voltage (TEV) Principle | Detects transient voltage signals to ground on the metal surface of the switchgear caused by internal partial discharge, reflecting the intensity and characteristics of the partial discharge. The sensor detection frequency range is 3 MHz - 150 MHz. |
Ultrasonic Principle | Uses an air-coupled ultrasonic sensor to detect ultrasonic signals generated by partial discharge, with the sensor's center detection frequency at 40 ± 1 kHz. |
Resolution | Transient Earth Voltage (TEV): 1 dBmV Ultrasonic (AA): 1 dBµV |
Linearity Error | Transient Earth Voltage (TEV): Not greater than ±20% Ultrasonic (AA): Not greater than ±20% |
Temperature and Humidity | -20°C to 80°C; 4% to 95%; |
Communication Parameters | LoRaor NB/GSM |
Dimensions: | 185 mm × 140 mm × 45 mm |
Power Supply | 3.6 V high-capacity lithium battery (19000 mAh) |
Installation Method | Magnetic suction type |
Feature Overview
WI-360 Intelligent Partial Discharge Monitoring Sensor
During the operation of the power grid, the maintenance and inspection of electrical equipment are critical tasks to ensure the reliability of power supply, reduce safety risks during inspections, extend equipment lifespan, and improve the return on investment for equipment assets. High-voltage switchgear and ring main units are key nodes in the distribution network, where partial discharge poses a significant threat to their stable operation. The partial discharge sensor monitors data such as ultrasonic waves, ground waves, temperature, and humidity in real-time for each high-voltage cabinet in the distribution room. When partial discharge exceeds the threshold, the status indicator turns red, and an alarm event is generated, recorded, and stored. Simultaneously, alerts are sent immediately via SMS, phone calls, WeChat, email, and audible-visual alarms.
