Save Time and Money
The success and profitability of an electric utility company depend heavily on accurate metering. If metering is faulty, inaccuracies will result in billing errors. These errors can exceed hundreds of thousands of dollars in lost revenue per year. That’s why it’s imperative that your company use reliable and accurate meter test equipment. With features that allow for greater speed, precision and convenience for your technicians, the PowerMaster® product line will meet all your electric meter testing requirements
Versatility in the Field
The three primary methods for field testing electrical meters can all be performed easily with our PowerMaster® line. All PowerMaster® site analyzers feature NIST traceable reference standards so you are compliant with all regulatory requirements.
- Customer Load – verify meter accuracy under real-world operating conditions. This allows your technicians to test functionality and accuracy under actual billing conditions, taking into account harmonics, imbalances, and extreme power factor.
- Phantom Load (controlled current source) – use a controlled sinusoidal current source with customer site voltages to check meter accuracy with this ANSI C12-compliant application. Testing points include Full Load (FL), Power Factor (PF), and Light Load (LL).
- Phantom Load (controlled current and voltage source) – perform thorough phantom load testing with both controlled sinusoidal current and voltage sources. This allows for fully isolated meter testing similar to laboratory conditions.
