The terminal is designed for use within an Inline station. The power measurement terminal is used to analyze AC power grids. You can use it in distribution systems for measuring current, voltage, and power as well as detecting distortion and harmonics. You can run the power measurement terminal in five operating modes. In “Basic measured values” operating mode, the power measurement terminal is used to acquire mains variables in three-phase mains. Mains variables are phase currents, neutral conductor current, phase and phase-to-phase voltages, active power, reactive power, and apparent power as well as the power factors of phases, energy flow directions, and frequency. The measured variables and operands are calculated in accordance with DIN 40110 Parts 1 and 2 (non-sinusoidal variables). In “Scanning measured values” operating mode, the power measurement terminal acquires the instantaneous values (scanning values) of a measuring signal. This measuring mode is used to analyze the waveform of the measuring signal. In “Heating current measured values” operating mode, the power measurement terminal monitors non-equivalence. Phase currents and phase voltages are measured to detect faults at an early stage. In the “1-phase or 3-phase synchronization” operating modes, the power measurement terminal acquires measured values that can be used for controlling the voltage, speed, and phase angle of a generator so that connection to the mains is possible.
