1…..Ground faults 2…..Arc Flash events
3…..Voltage fluctuation & imbalances
4…..Transients & Flash-overs
5…..Single phase Voltage Sags
Could the answer be?
At the worst possible time!
Problem: Circuit Breaker catastrophic failures. This picture shows the damage caused by arcing ground faults on a Work Boat. 8 Arc Flash events in 2 years, cause ABS to ground this vessel.
This circuit breaker is but one of many catastrophic failures & 8 Arc Flash events on this new Pipe Laying Work Boat, equipped with all of the latest protection systems, including *High Resistance Ground system *Ground Fault detection system *Harmonic Filters *TVSS, SPD, Lightning Arresters *Reactors *Phase Voltage imbalance relays *Zig-Zag transformers
- 500 amp Molded Case Circuit Breaker, destroyed by Arc Flash.
- As a result of this event, two electricians were sent to a hospital for treatment.
VSGR was installed, allowing the ship to sail!
There have been no Arc Flash events since!
