Besides, control functions are included as VT supervision, CT Supervision, Trip circuit monitoring or
breaker failure monitoring.
All models include a circuit breaker management block, which:
- Monitors the condition of the circuit breaker, the number of openings and accumulated amperes.
It generates an indication when there is an excessive number of openings and accumulated
amperes.
- Determines if an opening fault has occurred
- Allows circuit breaker opening and closing commands to be given from the HMI (using different
keys) and through local and remote communications
The following measurements are provided by the SIL-G equipment:
- Phase currents, neutral (measured and calculated), maximum current, positive sequence current
and negative sequence current.
- Second harmonic current per phase
- Simple voltages, phase to phase voltages, neutral voltage (calculated and measured), maximum
voltage, line voltage, positive sequence voltage and negative sequence voltage.
- Current angle for each phase and neutral (referred to VA)
- Voltage angle per each phase and neutral (referred to VA)
- Phase B Line voltage angle
- Active, reactive and apparent powers (3- phase and per phase)
- Thermal image
- Line frequency and busbar frequency
- Rate of change of frequency
- V/Hz related to nominal Vn/fn
Depending on model, the relay can include different slots regarding inputs and outputs:
The slots 3 and 4 include the inputs and outputs that depending on model offered:
- SILGxxxxxx0xxx: 7 outputs and 8 inputs. All the outputs and inputs are included in SLOT 3 , being
SLOT 4 empty.
- SILGxxxxxx7xxx: 11 outputs and 16 inputs. The 16 inputs are included in the SLOT 3 and the 11
outputs in the 4 .
