· Single-phase measurement of voltage, current, frequency, real power and apparent power
· Choice of measuring phase-to-ground or phase-to phase voltages
· Suppression of DC components and harmonics in current and voltage
· Compensation of phase errors in main and input c.t’s and v.t’s

Table 16: Three-phase measuring module
· Three-phase measurement of voltage (star or delta), current, frequency, real and apparent power and
power factor.
· Two independent impulse counter inputs for calculation of interval and accumulated energy. The three-
phase measurement and the impulse counters can be used independently and may also be disabled.
· This function may be configured four times.
