Problems we help solve

When your equipment raises questions, we help you get answers

Q01

We need a new substation built, or an existing one expanded.

Greenfield construction and modifications to existing substations, with commissioning so the equipment is tested and ready for service.

Q02

Is this transformer ready to energize?

New, repaired, and relocated units need acceptance testing and documented results before they go into service.

Q03

What is the condition of our equipment?

Electrical testing and oil analysis show how substation assets are aging, so you can plan maintenance and budget for it.

Q04

Our oil results came back poor. Now what?

Moisture, dissolved gases, and contamination can often be addressed with on-site oil processing instead of replacement.

Q05

Will the station stay protected if AC power is lost?

Substation battery banks keep relays and breaker controls working during an outage. Testing shows whether they are ready, and aging banks can be replaced.

Q06

Something tripped or alarmed. We need answers.

Field troubleshooting and diagnostic testing help find the cause and get equipment back into service safely.
