Vacuum Integrity Tests
The purpose of a vacuum integrity test is to confirm that the pressure in a vacuum interrupter is low enough for the interrupter to reliably perform its switching and insulating functions.
Unfortunately, measuring the pressure inside a vacuum interrupter directly is a very difficult task, which requires specialized equipment and even then, measurements can only be performed accurately on a vacuum interrupter by itself, not when it is installed in a circuit breaker. The use of a voltage withstand test to verify that the vacuum pressure is still within acceptable limits is, therefore, recommended.

Lot of Electrical youtube channels are there, But your contents are exclusively substation and it's equipments oriented in tamil. No one is doing particularly like yours with neat practical explanation.
Congrats keep going on to educate us through new contents 👏😊

Really Thanks Mr.Mohamed Askar
No words to say
Keep support you will get Good videos

What shall be the test voltage in DC for 6.6kV & 11kV Vacuum Circuit Breaker?

[@Engineering-in-tamil]

Common ah
We will give 2 times of Operating voltage

[@jasssimm8422]

What is the allowable leakage current sir ??

[@Engineering-in-tamil]

The allowable leakage current for a vacuum circuit breaker during a vacuum bottle test typically depends on the manufacturer's specifications and industry standards. It's crucial to refer to the specific technical documentation provided by the manufacturer or relevant standards
Normally it will be micro amps

[@g.udhayakumar5483]

Why you are applying DC volt to an AC breaker?

[@Engineering-in-tamil]

Thank you for your valuable Question Sir
We can apply AC or DC voltage no issue
When compare to AC voltage DC injection will give accurate result
Also AC v can do
our aim to measure Dielectric strength

Really Thank you

[@MTBZSebastian]

Sir, here we set micro Amps to 300, what is the criteria for selecting this value? And is it based on the Kv rating of breaker?

[@Engineering-in-tamil]

Breaker manufacturer recommendations
Generally we are taking reference value 300microAmps
