System Voltage is 4160 L-L
Grounding is Low Resistance / 10 seconds
Arrestors are 6 KV
PTs are Y-y 2400V to 120V Ratio 20 to 1
The 2400V PTs would be fine on a solidly grounded system, but not on a low resistance grounded system.
I think the PTs should be 4160V to 120V or 35 to 1 ratio ?
Am I thinking correctly ?
