19
Q

Always allow _________ for the capacitor to discharge

A

5 to 10 minutes

20
Q

A procedure that is not used to de-energize a capacitor bank is

A

Close the oil or vacuum switch

21
Q

Capacitor testing is usually used to find a existing problem rather than preventing a future problem

22
Q

How many moving parts does a capacitor have

23
Q

The 2 main parts of a capacitor to check are

A

Insulators and bleed resistors

24
Q

A ____________ is used to test a capacitor

A

Megohmeter

25
You can test the insulation’s conduction to see if you have a problem
True
26
The field test used to test insulation is called insulation resistance test
True
27
The function of insulation the to prevent current from flowing between the insulators and the ground
True
28
_____________ is the insulation’s ability to prevent current flow
Resistance
29
The purpose of a insulation resistance test is to identify if the insulation is the problem of the capacitor
True
30
A meeger applies AC voltage to one terminal in a de-energized capacitor
False
31
The insulation resistance test is used to test both bleed resistor and the insulators separately
True
32
Capacitors or installed at sun stations only
False
33
Capacitors can be hooked up wye or delta
True
34
Always check capacitors for bulging cases cracked or chipped porcelain and leaking oil before installing
True
