Field Testing & Inspection

The goal of our team is to compile the results and propose recommendations from a series of methodical and standards tests that help you make data-driven decisions about the necessity and priority of repairs, which can be used when planning and scheduling for outages and generator repairs. It will also help you evaluate the condition of your equipment in order to determine if replacement or upgrades are necessary.

​

Some of our generator testing and inspection services include:

RTD resistance testing with temperature conversion

Insulation resistance/Megger with Polarization Index (P.I.)

Impedance testing of the field

Copper resistance with temperature conversion to factory test temperature

Copper resistance of stator 3 phases converted to factory test temperature

Megger of stator 3 phases with P.I. as per IEEE Std 43

Visual inspection of all accessible areas

IR/Thermal Imaging

Pressure/Vacuum Testing

El Cid Testing

AC/DC Leakage and Hi-Pot Testing

Capacitance Mapping
