2.1 Overview
SICAM Feeder Condition Monitor (FCM) is an Intelligent Electronic Device (IED) used for detecting and indi-
cating short circuits or ground faults with and without directional information. SICAM FCM accurately moni-
tors, measures, and displays operational measured values and performs the condition monitoring task in a
medium-voltage distribution system. SICAM FCM is typically used in the medium-voltage and low-voltage
secondary substation that ranges from 0.4 kV to 36 kV.
SICAM FCM measures the RMS value for alternating voltage, alternating current, and power frequency.
SICAM FCM calculates the active power (P), reactive power (Q), apparent power (S), power factor (cos φ),
phase angle, energy, and other relevant values.
SICAM FCM consists of the following hardware interfaces:
•
3 current inputs
•
3 voltage inputs
•
1 digital input
•
2 digital outputs
•
1 RS 485 interface (Modbus RTU)
•
1 auxiliary power supply
