We use in our power plant generator circuit breaker type ABB HMB 4.5 2CO and i have problem with the pump.
The pump is not working for a long time (days).
Can you explain somebody if i take a trip the breaker will open? Do i have sufficient hydraulic oil pressure to have a breaker opening in case of a trip? How can i understand that i have enough oil pressure to open the breaker?
All i can see is the energy storage device, position (compressed-expanded) through a small window. In what position should it be?
