Three phase single source prepaid Energy Meter

A Three Phase Single Source Prepaid Energy Meter is an advanced electricity metering device used to measure and monitor the energy consumption of a consumer connected to a three-phase electrical supply system. It operates on a prepaid model, meaning the consumer must pay for electricity before using it.

Key Features:

1. Three-Phase Measurement:

   • Accurately measures voltage, current, power factor, frequency, active/reactive energy across all three phases.

   • Suitable for commercial, industrial, and high-load residential installations.

2. Prepaid Functionality:

   • Electricity must be purchased in advance (via token, card, or digital platforms).

   • Prevents energy theft and helps users manage electricity budgets.

3. Single Source:

   • Connected to a single incoming power source (typically from a utility provider)

        • Compatible with utility backend systems for automatic data collection and billing.

     3. Tamper Protection:

        • Alerts and logs for events such as magnetic tampering, reverse energy flow, and terminal cover opening.

     4. Disconnection & Reconnection:

        • Automatically disconnects the supply when credit runs out.
