Lightning Arrester Testing Service
When a lightning surge travels along the power line to the arrester, electricity from the surge is diverted through the arrester to the earth. If protection fails or is absent, lightning that strikes the electrical system introduces thousands of kilo volts that may damage the transmission lines, and can also cause severe damage to transformers and other …

Typical rod gap arrester Limitations After the surge is over, the arc in the gap is maintained by the normal supply voltage, leading to short-circuit on the system. The rods may melt or get damaged due to excessive heat produced by the arc. The climatic conditions (e.g. rain, humidity, temperature etc.) affect the performance of rod gap arrester.
