3-Phase, 4-Wire/ Commercial & Industrial

The Byram meter is a very accurate revenue meter (0.2 accuracy Class). The meter provides advanced four quadrant revenue functions, transformer and line loss compensation, and increased data profiling without adding hardware option boards. The main circuit board has a nonvolatile memory for storing profile, data logs, and self read data. If extensive profile recording is required, an extended memory option board can be easily added to increase total memory by 1 MB. When optional instrumentation profiling is enabled, the meter stores 2 separate sets of instrumentation data. Each data set has an independent interval length and up to 16 channels. With instrumentation profiling, each meter becomes a powerful data collection tool to monitor data and diagnose problems without installing expensive temporary monitoring equipment.

Power Quality Management

Power quality management (PQM) provides continuous service condition monitoring 24 hours a day. PQM looks for exceptions to user-defined thresholds for items such as voltage, current, and total harmonic distortion. Each of the 12 PQM tests can be configured to control relay activation, LCD warning, date/time stamp log entry, and even an automatic telephone call to report the condition.
