• Meter, Transformer & Wiring Testing
• True 3-phase Analyzing Reference Standard
• Internal Current & Voltage Source
• More accurate than most lab standards
The PowerMaster® 7 Series is a Complete Field Meter Site Testing Solution
A true 3-phase analyzing reference standard with internal 3-phase current and voltage source capability.
he 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.
