The relay continuously measures the phase currents and the neutral current. Furthermore, the relay measures the phase voltages and the residual voltage. In addition, the relay calculates the symmetrical components of the currents and voltages, the system frequency, the active and reactive power, the power factor, the active and reactive energy values as well as the demand value of current and power over a userselectable preset time frame. Calculated values are also obtained from the protections and condition monitoring functions of the relay.
The relay is also offered with RTD/mA inputs and can measure up to 16 analog signals such as stator winding and bearing temperatures via the 12 RTD inputs or the four mA inputs using transducers.
The measured values can be accessed via the local HMI or remotely via the communication interface of the relay. The values can also be accessed locally or remotely using the Web HMI.
The relay is provided with a load profile recorder. The load profile feature stores the historical load data captured at a periodical time interval (demand interval). The records are in COMTRADE format.
