Three-Phase LT Transformer Operated Static Energy Meter 37 CM

  • VISIONTEK 37 CM Three Phase Electronic Energy Meter is a CT operated trivector meter designed to meet the energy metering requirements of high power consumers. The meter is targeted at the deregulated energy markets which require flexible tariff structures and a modern energy management.

    37 CM is a perfect combination of well-proven metering technology sealed in a single enclosure with multiple communication interface options.  The intelligent features of detecting and recording different anomaly conditions and cover opening events make it ideal choice for revenue protection for distribution companies.

    37 CM is suitable to deploy for industrial consumer (LT) revenue metering and distribution transformer metering for audit purposes. Meter complies with IS and IEC Class 0.5S metering standards, CBIP 325 and communication protocol in accordance with IS 1959 (Part-1) with the latest amendments as Category C1 for communication interoperability.
