Revenue Protection Through Field-Based Meter Site Analysis
Why Meter Accuracy Alone Isn’t Enough
Every electric bill represents a financial transaction: energy is consumed,
payment is exchanged, and both the utility and the customer expect it
to be fair. Utilities invest heavily in meter testing programs to ensure
meters meet regulatory and ANSI accuracy requirements. However,
meter accuracy alone does not guarantee accurate billing.
A revenue meter can pass every laboratory test and still produce an incorrect bill once installed
in the field. That’s because the meter is only one component of a much larger measurement
system that includes wiring, current transformers (CTs), potential transformers (PTs), test
switches, burden, and billing system configuration.
Field-based meter site analysis evaluates the entire system under real-world conditions,
uncovering issues that shop testing alone cannot detect.
