State the difference between Surge Arrester and Lightning arrester,Both are same or not?..

Answer / faisal

Surge Arresters are widely also known Lightning arresters.
However strictly speaking the two are in fact different. Surge arresters are devices installed on Over head lines, substations etc to avoid a surge of an additional current/ voltage/charge due to various faults occurring and since one of the major reasons of a surge is due to lightning these surge arresters are also coined as Lightning arrester.
However Lightning arresters are separate instruments specifically designed for protection of structures solely from lightning this equipment neutralizes the charge by nullifying the charge it receives from the lightning and grounds it.Lightning arresters don't intervene with the excess current / voltage surge due to electrical faults - it is solely for LIGHTNING protection unlike surge arrestors which is a protection against electrical faults and Lightning which is a natural charge dispenser

Answer / hms

The main differences between a lightning arrester and a surge arrester are time and position. In the past, there were only lightning arresters, since lightning was the only place where big power surges would come from. Now, a lighting arrester typically prevents surges from outside the electrical grid, and a surge arrester prevents ones from inside.
"Both are doing the same job,but both are not same".

A surge arrester is device that intercepts electrical surges and sends the spike to ground before it can hurt a connected device. These arresters are also known as surge protectors or lightning arresters, but there are some very small differences between these devices. In most cases, when a surge arrester intercepts a power surge, it fuses itself to prevent transmission. This will stop the surge, but it also destroys the surge arrester. If the arrester is improperly installed, this fusion can cause more problems than the initial surge.

Answer / priyanka dhar

Lightning arresters are installed inside the distribution
board and they protect against surge volatges in case of
direct lightning strikes.

surge arresters are installed in sub-distribution board as
well as in terminal equipment thus protecting against surge
voltages due to distant lightning and due to internal
switching operations respectively.

there is a power transformer 66/11kV in delta-delta connection has 5 feeder coming out from the secondary side. One of the feeder in it normally loaded (loaded than other feeder)and this feeder usually trips with double OCR causing the bank transformer to trip. Now if the load of this feeder is put on other transformer then that no problems occurs on that transformer or the load. However normally all the test(IR, PI, short ckt, open ckt,grounding test and other ) has been conducted for this but evertything transformer..... I am not geting what is the actual problem...
