How to HT breaker vacuum bottole integrity test

Question

Accepted Answer

HT breaker vacuum bottle integrity test is performed to ensure the vacuum bottle is free from leaks and can withstand high voltage.

The test is performed using a vacuum pump and a pressure gauge.
The vacuum pump is connected to the breaker's vacuum bottle and the pressure gauge is connected to the pump.
The vacuum pump is turned on and the pressure gauge is monitored for any drop in pressure.
If the pressure drops, it indicates a leak in the vacuum bottle.
The test is repeated multiple times to ensure accuracy.
If the vacuum bottle passes the test, it is considered safe for use.
Regular maintenance and testing of the vacuum bottle is important to ensure safe operation of the breaker.
