The Harmonic Analysis option makes it possible to analyze loads through the 64th harmonic order. A built-in Comparator option provides automatic calculations of test results for the meters and standards being tested.
The RD-33 can be used with a controlled current source to test revenue meters and reference standards. In field applications, the RD-33 can perform a true three phase meter accuracy test using an existing service load. Pickups to sense meter disk rotation or calibration pulses of infrared, visible light or KYZ variety plug directly into the unit.
The RD-33 is ideal for testing high-end energy meters found in power plants, substations, inter-tie points and at large utility customer accounts. The RD-33 is also the perfect complement to relay test sets where it can serve as an active reference standard when testing meters or can be used to periodically certify the accuracy of the test set itself.
