) - This is a measurement of the insulation on Phase 2 (B) between

Pole 3 and Pole 4 with the circuit breaker in the open position. All other poles

on the breaker will be floating (no connection). The HV cable will be connected

to the bushing top terminal of either Pole 3 or 4. The LV Red lead is connected

to the other Pole. The frame of the breaker must be connected to station

ground. Test mode is UST-R.

Test 9 (C

) - This is a measurement of the insulation on Phase 3 (C) between

Pole 5 and Pole 6 with the circuit breaker in the open position. All other poles

on the breaker will be floating (no connection). The HV cable will be connected

to the bushing top terminal of either Pole 5 or 6. The LV Red lead is connected

to the other Pole. The frame of the breaker must be connected to station

ground. Test mode is UST-R.

Test 10 (C

+ C

) - This is a measurement of the ground insulation on Phase 1

(A) with the circuit breaker in the closed position. All other phases on the

breaker will be floating (no connection). The HV cable will be connected to the

bushing top terminal of Pole 1 or 2. No LV lead connection is required. The

frame of the breaker must be connected to station ground. Test mode is GST-

GND.

Test 11 (C

+ C

) - This is a measurement of the ground insulation on Phase 2

(B) with the circuit breaker in the closed position. All other phases on the

breaker will be floating (no connection). The HV cable will be connected to the

bushing top terminal of Pole 3 or 4. No LV lead connection is required. The

frame of the breaker must be connected to station ground. Test mode is GST-

GND.

Test 12 (C

+ C

) - This is a measurement of the ground insulation on Phase 3

breaker will be floating (no connection). The HV cable will be connected to the

bushing top terminal of Pole 5 or 6. No LV lead connection is required. The

frame of the breaker must be connected to station ground. Test mode is GST-

GND.
