    IDMT characteristics are defined as Inverse because the trip time is inversely proportional to the fault current being measured. In SICAM FCM, the IDMT function supports the Normal Inverse (NI) characteristics. The ANSI codes supported by the IDMT function are non-directional (51) and directional (67) for overcurrent indication.

  • Page 40: 3-Phase Angle Calculations

    The phase sequence of the measured phase-to-ground voltages is checked by monitoring the angle difference between phase-to-ground and phase-to-phase voltages. SICAM FCM monitors the phase sequence of voltage signals from voltage sensors and displays it on the HMI/ Modbus. The phase-sequence monitoring algorithm uses measured phase-to-ground voltage and phase-to- phase voltage angles in balanced condition.

  • Page 41: Determination Of Fault Direction

    If there are any device alerts and a fault is detected in the system, then the phase sequence is displayed as --- on the HMI and the Modbus register is set to 0. NOTE Protection functions implemented in SICAM FCM are designed for clockwise phase sequence only. Determination of Fault Direction 4.1.15 The fault direction for the phase faults is determined by calculating the phase angles between the fault current and the corresponding phase-to-phase voltages.
