The Powermate Power System Analyzer is a self-contained, state-of-the-art, portable field tester that combines all of the features needed for field Wiring Verification, Meter Accuracy, Revenue Protection, and even Power Quality testing. Its lightweight design, battery-powered operation, graphical displays, and easy-to-use menus not only allow quick verification of meter service wiring and total loop meter accuracy but also detailed analysis of installation components (i.e., wiring, CTs, VTs) if a problem is found.

ERCOT SPECIFIC TESTS:

3.5 Secondary Wiring: directly tested along with the CTs (see CT testing above)

4. Voltage Transformers: The Powermate can calculate the actual VA burden (total loop) by measuring the VT secondary current and the VT voltage. If the VT secondary terminals can be accessed, the voltage drop across the ENTIRE secondary loop can also be measured.

6. Testing and Calibration: The Powermate embedded true 3-phase standard can field verify the accuracy of a meter to better than 0.05% at ANSI test points using direct current from test switch connections. The Powermate can be readily calibrated against a utility reference standard as frequently as desired using the normal field Meter Test function.

6.5 Calibration Tolerances: The Powermate 730A can automatically test a meter for 3-phase registration at FL, LL, and PF as well as for phase balance. Testing can be performed for W-hr and VAR-hr, delivered or received, without changing the test configuration or field jumpers.
