SNV-308 Overhead type earthing and short circuit fault indicaor
SNV－308 is suitable for overhead line 35KV and below a four remote function grounding and
Short-circuit fault indicator.SNV－308 through real-time measurement and according to the current
Cable current waveform changes to determine the short-circuit fault on the power lines and
Grounding fault, and the fault state, real time current (fault current), battery voltage, temperature,
Electric field of cable and other information uploaded to the remote server, which provides reliable
Data for the various types of fault diagnosis and location overhead line.
SNV- 308 by handheld PDA in the process of using (SNV- 307) or communication terminal
(SNV- 309) for its flexible configuration to meet the needs of different environment monitoring
Overhead.
