Earth Fault Indicator (EFI)

Next generation three phase fully programmable smart energy meter with robust performance of high accuracy, high reliability, wide measurement range, and low power consumption, etc. The meter is fully compliant with IEC 62052-11:2020, IEC62053-21:2020, IEC62053-23:2020 and IEC62052-31:2016, OIML and DLMS/COSEM standards, allowing billing and management applications in IEC compliant countries for residential, commercial and industrial energy measurement and management.A Transformer Operated measurement (CT Connected) meter, covering wide voltage range of AC active/reactive energy with frequency of 50/60Hz. It can provide bi-directional communication with advanced information to utility data management system and end-customer, It can be read locally using HHU via optical port, as well as remotely via modular communication channel of PLC/RF/GPRS/GSM/LTE/NB-IOT installed in meter body under a sealable cover and connected to meter mainboard thru serial port, which make it possible for remote data access by DCU or MDCS. It also supports to control an External circuit breaker (ECB) via Output relay or RS-485 (Using RJ-45 connector) over MODBUS. The meter is designed with a built-in GPS modem which can triangulate signal from GPS satellite to position the location of the meters installed and push to the HES.
