ELECTRICAL TESTING / PREVENTATIVE MAINTENANCE
"AN OUNCE OF PREVENTION IS WORTH A POUND OF CURE"
BEN FRANKLIN
Ideally, site specific programs should include regularly scheduled inspections, electrical testing, maintenance, detailed reporting and trending of equipment health. These preventative measures will ensure that your facility runs optimally for years to come. We align ourselves with NETA standards, so you know you're getting the right results each time.

ELECTRICAL TESTING
NETA CERTIFIED ACCEPTANCE TESTING / COMMISSIONING
There is no better preventative measure than making sure your equipment is working correctly from the start. Acceptance testing catches issues before they are major problems, including defective equipment, wiring errors, loose connections, missing and incorrect coordination studies, shipping damage and installation errors.
BENEFITS

Catch problems BEFORE they become
catastrophic failures!
TRANSFORMER TESTING / OIL ANALYSIS
Fluid filled transformers, tap changers and circuit breakers contain high quality oil that serves as an insulator and coolant. Yearly oil testing will not only verify condition, but also detect internal problems and impending failures. Oil samples can usually be procured without a power shutdown, thus providing a valuable and cost effective maintenance tool.
OIL ANALYSIS
ASTM - SIX PART TESTING
dielectric breakdown, moisture content, color,
acidity, interfacial tension, specific gravity
DGA
dissolved combustible gases in oil
TCA
transformer condition assessment
TASA

TROUBLESHOOTING / EMERGENCY SERVICE
When the unexpected occurs, our regular maintenance customers know they can turn to us. Our technicians are trained and experienced in troubleshooting whole systems. What sets us apart from other testing companies is our proven track record in resolving issues timely and effectively.
Many times, our in house parts procurement department allows us to offer on site repairs without the need for factory service. When available, we use new OEM parts and perform post repair electrical testing, ensuring proper equipment operation prior to returning to service. If new parts are unavailable we have long standing relationships with many resellers of used and refurbished OEM parts and equipment.
