SWITCHGEAR PARTIAL DISCHARGE ONLINE MONITORING DEVICE

"The switchgear partial discharge online monitoring device is based on the ultrasonic (AE) principle, transient earth voltage (TEV) principle, and ultra-high frequency (UHF) principle. It acquires discharge pulse signals in real-time, converts and calculates them through detection, and outputs the discharge amplitude. The AE sensor has a frequency of 40 kHz and a monitoring range of 060 dB; the TEV sensor has a detection bandwidth of 1100 MHz and a monitoring range of 060 dB; the UHF sensor has a detection bandwidth of 3001500 MHz and a monitoring range of -80 to 0 dB. The device features a built-in LCD screen to display real-time partial discharge monitoring values and curves for all three principles.

MATERIAL TRANSPORT MONITORING TERMINAL

New Products / New Technology

The logistics‑transport monitoring terminal is a device designed to track the status of shipments during transit. It provides real-time monitoring of parameters such as vehicle speed, location, impact acceleration, battery level, temperature and humidity, and tilt angle, and transmits this data via an encrypted 4G network to the State Grid Power Logistics Service Platform. Logistics managers can then view and manage transport tasks in real time on the platform. The battery offers up to 90 days of standby time, making it well suited for long‑distance transportation.
