The Selection Of Surge Arresters In Monitoring Systems Should Be Based On The Differences Between The Location And The Protected Object.

For scenarios involving long cable lengths, metal pole supports, and signal lines running through metal conduits, the 33 kv lighting arrester cable should be positioned close to the signal entry point and connected to the grounding system at equipotential to accommodate high induced voltage on the transmission line. According to relevant industry data, installing a 33kv lightning arrester price cable before the signal/control line enters the chassis can significantly reduce lightning surge paths. Inside the computer room, the 33kv surge arrester cable at the entry point of power lines, video cables, or Ethernet cables should be routed in conjunction with the protective ground of the monitoring main control equipment. The routing for high-voltage surges during line cuts differs from that for outdoor extension lines.
