Power Master® 7 Series

The PowerMaster 7 Series as a true 3-phase analyzing reference standard with internal 3-phase current and voltage source capability.

The innovative design of the PowerMaster® 7 Series allows utilities to fully test a metering installation with one piece of equipment. Customer load meter testing, phantom load meter testing, CT burden and ratio testing, CT de-magnetization, PT ratio testing, and transducer testing can all be performed with one solution. In addition, vector diagrams, voltage and current waveforms, and harmonics data up to the 100th harmonic can all be analyzed to complete a true wiring verification.
