Working Principle The module receives voltage signals from potential transformers (PTs) and current signals from current transformers (CTs) in the power distribution system. Internal signal conditioning circuits scale and isolate these high-level signals. A digital signal processor calculates RMS values, frequency, phase angle, and power quality parameters. Digital inputs monitor breaker auxiliary contacts and switch positions. All data is transmitted to the control system for display, alarming, and control actions such as automatic voltage regulator (AVR) adjustments or protective tripping.
