PRODIGY

DISTRIBUTION TRANSFORMER METER

Prodigy is a genuine innovation in the field of three-phase LV CT-operated metering. It is an integrated meter with built-in current transformers, eliminating the need for external CTs and
accessories. Prodigy is based on the unique concept of threadthrough connections, which helps maintain overall system accuracy and revenue integrity. 

Applications :
    1. Distribution transformer (DT) metering
    2. Energy audit and system analysis
    3. Low-voltage high-current commercial metering

Features :
    1. True four-quadrant metering
    2. Programmable time-of-use (TOU) tariffs and maximum demands (MD)
    3. Thread-through arrangement: field cable passes directly through the meter
    4. Large backlit LCD with phase indicators and parameter identification
    5. Display scroll lock for continuous display of desired parameters
    6. Logging of billing data and multi-parameter load survey
    7. Special load-profiling and event-logging for energy auditing
    8. Optional inductively-coupled external power pack for meter reading in the absence of mains supply

Benefits
   1. Better overall system accuracy than a traditional meter and associated CTs
   2. Easier to install than traditional DT metering
   3. Reduced cost for equipment, installation and maintenance by eliminating the need for external CTs, meter enclosure and accessories
   4. Increased reliability and tamper resistance compared with traditional installations
   5. Easy diagnosis of installation faults via a complete set of instantaneous electrical parameters
