Project is to verify the EMF meters as per standard

Device which is used to measure the hazardous gas and transmts to control system over HART and Modbus 

To control the light using DALI protocol 

CL7 Regulator is single phase step voltage regulator which has motor driven Tap changing autotransformer. It provides constant monitoring of the transformer voltage and generates a RAISE or LOWER control signal to the motor drive of the tap changer when the measured voltage differs from pre-set values. It include built-in metering, voltage limiting, voltage reduction, reverse power flow detection and operation, time-tagged demand metering, profile recorder, tap position tracking, and source voltage calculation without an additional potential transformer.
