PEC.300C Three Phase Power Meter Calibrator

The PEC.300C is a high-precision 3-phase power meter calibrator designed for laboratory and field verification of energy meters, indicating instruments, and electrical parameter measurement circuits. It integrates meter calibration, electrical parameter analysis, wiring inspection, waveform display, harmonic analysis, and data logging, making it a complete power measurement diagnostic system for utilities, service companies, and metrology centers.

Key Features

  • High-accuracy calibration of single-phase & three-phase energy meters

  • Supports real-load online testing without breaking circuits

  • Measures: voltage, current, active/reactive power, frequency, phase angle & power factor

  • Vector diagram display and automatic wiring judgment (48 connection recognition modes)

  • Clamp-on current transformer support for non-intrusive current verification

  • Displays single-phase or three-phase waveforms simultaneously

  • Power quality analysis of waveform distortion, harmonics & network imbalance

  • Stores up to 1000 test records with timestamp and export capability

  • Optional virtual load box for testing meters under no-load/low-load conditions
