What is an acceptable value of 132kv Isolator contact resistance test?
132kv MOCB acceptable value of somthing 150 micro ohms.
Must a 22KV Switchgear step-down with a 22KVA trasformers?
A 22 kV switchgear does not necessarily need to step down using 22 kVA transformers. The switchgear can be used in conjunction with transformers of various ratings depending on the load requirements. The transformer rating should match the load it serves, and the switchgear is designed to handle the voltage and current levels of the system. Therefore, the choice of transformer depends on the specific application and load characteristics rather than being strictly tied to the switchgear voltage.
How the voltage regulation in 33kv line?
It does not depend on the line. The regulation is the percentage change in voltage caused by applying the full load current, and that depends on the transformer supplying the line. A value of 5% would be typical.

Is a series inductive reactor a switchgear?
'Switchgear' is a generic term for all switching devices, such as circuit breakers, isolators, air-break links, etc. A reactor is simply a coil so, no, it is not classified as being switchgear.
What is the name for a collection of switchgear in the context of electricity distribution?
I don't know of a formal name, but in the trade we refer to it as a "switchgear bank".
What is the most common type of switchgear?
Metal-clad switchgear assemblies are the most common devices used in electricity distribution.
What is A preestablished value indicating a level of acceptable practice?
The answer is a Threshold Value
