Automatic Changeover Switching Equipment (ACSE)

The automatic control function is responsible for the automatic switching scheme and interlocks for breakers. In order to achieve this function, the intelligent electronic device (IED) collects inputs for breaker status, protection relays, and other data related to power such as voltage and volt-ampere reactive (VAR) values. This function is derived from the same IED used in the panel to divert the control through the supervisory control and data acquisition (SCADA) system.

Automatic Bus Transfer Scheme (ABTS)

The automatic bus transfer scheme (ABTS) is an automatic switching scheme in substations which performs in parallel with some transformers. In the event of a power transformer failure, the remaining transformers continue to operate to feed the entire substation load without interruption of supply. The ABTS scheme can be achieved through a programmable intelligent electronic device (IED) or remotely controlled through the supervisory control and data acquisition (SCADA) system.

Automatic Capacitor Control System (ACCS)

The automatic capacitor control system (ACCS) provides automatic control for capacitor banks to improve the power factor and reduce the volt-ampere reactive (VAR) value in the network, thereby helping to reduce losses in power lines, the control logic performed by gathering voltage, current, and breaker status of the busbar and the incomers. This control can be achieved through a programmable control intelligent electronic device (IED) which can calculate the VAR values and drive a logic based on these values.

Automatic Voltage control (AVC / RTCC)

Automatic voltage control monitors the voltage of a power transformer and keeps the load voltage in the controlled setting value. This control is performed using a control intelligent electronic device (IED) which sends control output to a tap-changer for the transformer. A signal can be sent to raise or lower the tap, depending on voltage setting.
