● Power: DC 12-36V ● Measurement content: AE, TEV, UHF, Noise, Temperature, Humidity ● AE range: 0dBuV~60dBuV ● TEV range: 0dBmV~60dBmV ● UHF range: -70dBm~10dBm ● Temp range: -40°C~85°C ● Communication: RS485 (MODBUS-RTU) ● Installation: Magnetic
APD series high-voltage switchgear partial discharge monitoring device detects the electromagnetic wave radiation generated along with partial discharge and automatically determines the actual detection frequency of on-site partial discharge. Then, data such as the number and frequency of partial discharge detected are uploaded to the server.
