6th Step

Question 1

Switched cap banks may be switched automatically based on?

Answer 1

Vars 
Voltage 
Amps
Time and date 
Temperature up

Question 2

After opening a cat bank how long must you wait before closing it? Why?

Answer 2

A minimum of five minutes

Because that’s how long it takes for the resistor inside the cap bank to bleed off the left over capacitance voltage that’s left over in the cap after de-energizing

Question 3

Pre rigged switches can only be rigged to open or close?

Answer 3

Open

Question 4

What must the neutral have at an AR if there is phase to neutral load beyond the AR?

Answer 4

The neutral must have a CT on it at the AR

Question 5

Can you ground the neutral beyond an AR? Why?

Answer 5

No, escaping current

Question 6

Why do we install AR’s?

Answer 6

Sectionalizing-bad acting circuits

Protection- far from the sub, can’t create enough phase to ground fault current

Change mode of operation- bulletin 322

Question 7

I’m a bulletin 322 area during red flag warning what must be done before re-energizing?

Answer 7

The circuit must be patrolled

Question 8

Why do we have ground banks?

Answer 8

Gives a delta circuit ground protection and also to stabilize an ungrounded neutral

Question 9

3 mechanisms PE gear need to function?

Answer 9

Transfer mechanism ( the arm that moves )

Control mechanism ( control box )

PT ( preferred side has a 3 phase bank to sense voltage )
