Precision Three-Phase Power Measurement with the Potric PTS788
Designed for industrial plants, commercial buildings, and electrical submetering panels, the Potric PTS788 Three-Phase Electronic Energy Meter provides high-accuracy monitoring of active electrical energy consumption[cite: 2]. Built around advanced digital sampling technology, it measures phase voltages and currents accurately across wide operating environments while resisting electromagnetic interference.
Advanced Monitoring & Phase Indication
The meter features comprehensive diagnostic indicator lights on the front panel to ensure seamless maintenance oversight:
- Phase Loss Indication: Dedicated yellow, green, and red indicator lights signal phase voltage status; a deactivated light instantly highlights a phase drop[cite: 1].
- Reverse Current Warning: Built-in phase sequence indicators alert operators to reverse energy flow conditions[cite: 1].
- Impulse Output: Active testing output via photoelectric coupling enables fast calibration and accuracy verification[cite: 1, 2].
Engineered for Industrial Durability
Housed in a compact, flame-retardant DIN-rail / wall-mountable enclosure, the PTS788 is built to withstand rigorous operating conditions. With a wide temperature tolerance, long-term data retention exceeding 25 years[cite: 1], and robust surge isolation, it represents the ideal metering solution for modern electrical distribution infrastructure.
