SATEC’s EM133 NMI-approved product incorporates many advanced features, with Accuracy Class 0.5S offering extensive capabilities for a DIN-rail smart energy meter compliant to NMI M 6. With the EM133 meter, the company has achieved many challenging requirements of the NMI standard, including 12 kV impulse testing.

Following on from experience gained with the meter, SATEC is developing its branch feeder monitoring technology to meet the requirements of electricity metering for NMI trade measurement. The company’s current design BFM136 branch feeder monitor provides for 36 current inputs, configured for 36 single-phase circuits, 12 three-phase circuits or a combination of both for up to 36 current inputs using SATEC-designed current sensors (HACS). The HACS are designed as solid- or split-core for the 3000 A measurement range, providing high performance at low loads.

The branch feeder monitor provides real-time multifunction metering capabilities, tariff energy metering and time of use (TOU) along with event logging, data logging with date/time stamp. Standard communications include RS485 and TCP/IP connection for use with third-party software or the company’s energy management, billing and power-quality software eXpertPower. 

All SATEC metering hardware is supplied with the free licence software PAS for programming and downloading of log files in either Excel (.xls) or database (.mdb) format.
