Diagnostics
Common failures and what they mean
Equipment failing early
Voltage imbalance, undervoltage or harmonics shorten motor and compressor life. Power quality measurement identifies it.
Hot spots in panels and switchgear
Infrared scanning finds loose or corroded connections before they become arc flash events or fires.
Not enough capacity for new equipment
Load studies and service evaluations tell you what your facility can support before you buy equipment.
