Supply Disconnect and Reconnect
Load Limiting
The SGM1430-B meters support automatic disconnection of supply if the
delivered power from the network to the customer exceeds a predefined average
threshold over a predefined period of time.
When this functionality is enabled, the service will be disconnected for a defined
period of time if the average consumption over the configured period of time
exceeds the configured threshold.
Under/Over Frequency
The SGM1430-B meters support disconnection of service if the supply frequency
goes above an upper limit or below a lower limit.
When this functionality is enabled, the contactor will be disconnected for a
defined period of time if the average frequency over a configured period of time
exceeds either of the configured thresholds.
Sag/Swell (Short Term)
The SGM1430-B meters support disconnection of service if the supply voltage
goes above an upper limit or below a lower limit.
When this functionality is enabled, the contactor will be disconnected for a
defined period of time if the average voltage over a configured period of time
exceeds either of the configured thresholds.
Under/Over Voltage (Long Term)
The SGM1430-B meters support disconnection of service if the supply voltage
goes above an upper limit or below a lower limit for an extended period.
When this functionality is enabled, the contactor will be disconnected for a
defined period of time if the average voltage over a configured period of time
exceeds either of the configured thresholds.
Over Current
The SGM1430-B meters support automatic disconnection of supply if the
measured current exceeds a predefined average threshold over a predefined period
of time.
When this functionality is enabled, the service will be disconnected for a defined
period of time if the average current over the configured period of time exceeds
the configured threshold.
Power Factor
The SGM1430-B meters support automatic disconnection of supply if the
calculated power factor goes below a predefined average threshold over a
predefined period of time.
When this functionality is enabled, the service will be disconnected for a
configured period of time if the average consumption over the configured period
of time is less than the configured threshold.
