Helping Our Customers

At Three-C, we provide solutions that help our customers operate efficiently. Here is a recent success story:

Emergency Switchgear Replacement:
Three-C Electrical recently responded to an emergency call from a light industrial company. They had suffered an explosion in their Main 5kV switchgear and were without power to their entire site. Our initial investigation found that one of their 5kV switches had experienced an arc fault and subsequently went to ground. The resulting arcing and fire had compromised the rest of the switchgear, the cables and several low voltage switchboards. In addition, the three single phase utility transformers had overheated and were damaged by the event. The company's entire power feed system was destroyed. Find out more...

Arc Flash Project:
Three-C Electrical Company has a staff of electrical engineers with training and experience delivering power system studies to a wide variety of industries.  Our engineers utilize the latest version of SKM software, to deliver electrical arc flash hazard analysis studies that comply with NFPA-70E, and IEEE-1584. 

Deliverable-

Three-C Electrical performed a plant wide data investigation and analysis of the plant's power system equipment.  An Arc Flash study was delivered, which included results of the evaluation in tabular form, listing maximum incident energy, safe approach distances and PPE recommendations, arc flash equipment labels. 

Outcome-

The plant was able to comply with OSHA requirements for worker safety.  Three-C has continued to support the plant as changes/modifications are made to the plant electrical system, which impact the arc flash study.  Three-C has worked with the plant to develop an on-going maintenance program for their electrical equipment.  Three-C has provided electrical equipment maintenance and arc flash training for this plant on an on-going basis.
