I have been contacted by a government agency which is having control equipment damaged.
They say that a new 34,500/7,200 sub-station has been built to handle a large number of buildings. The buildings are military and use computers, HVAC, lighting and office space.
It is my understanding that twice there has been two didderent fuses at the sub-station blow. Both times there were numerous control voltage (120) coils and control transformers destroyed. The transformers are 480/120. They also say that on neither occassion did any motors, computers, lighting or any other building equipment become damaged.
Could there be a damaged sub-statioon transformer or grounding issue. The sub-station and buildings all sit on one of the highest hills in the area.
I would appreciate any help as this problem shuts down multiple buildings.
Thank You!
