Key attributes
| Brand | Rw Energy |
| Model NO. | UHF Partial Discharge Detector |
| Rated frequency | 50/60Hz |
| Series | APD100 |
Description
General
The 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.

Millisecond fault capture：cable O&M enters the digital era distributed cable fault location solutionThis solution leverages a distributed cable fault locator built on high-frequency travelling-wave acquisition + edge computing + travelling-wave time-difference positioning algorithms.It delivers instantaneous fault capture, metre-level distance measurement, AI-driven fault-type classification, 5-minute alarm push, and 24/7 online monitoring – closing the full "capture → locate → diagnose → alert → trace" loop.The result: high-voltage cable O&M shifts from reactive post-fault investigation t
FAQ for UHF Partial Discharge Detector
Specially designed for 10kV~35kV switchgear, transformers, and cable terminals. Timely treatment of partial discharge is necessary to extend equipment lifespan and avoid major repairs. Specially suitable for use in substations and factory distribution rooms, serving as a sentinel for power safety.
Super simple! Install the guide rail and connect the coaxial cable. Supports RS485 and Lora wireless communication, with data directly transmitted to the monitoring system. Debugging can be done in a few minutes without the need for a professional electrician, even small businesses can install it themselves.
UHF technology accurately captures the discharge electromagnetic waves inside the switchgear, with an accuracy of -60dBm to+10dBm. Automatic identification of discharge type and location is more accurate than traditional methods, providing early warning of equipment hazards, avoiding unexpected power outages, and ensuring factory safety.
