The panel typically includes a set of metering and protection devices, such as ammeters, voltmeters, frequency meters, and circuit breakers, to monitor the status of the power sources and ensure safe operation. It also includes synchronizing and load sharing devices such as synchronizing relays, voltage regulators, and load sharing controllers that allow the power sources to be connected and disconnected to the bus in a controlled and coordinated manner.
The synchronizing panel also includes a control system that monitors the status of the power sources, compares their voltage and frequency, and makes decisions on which sources to connect and disconnect from the bus. The control system can be manual or automatic, and can also provide alarms and status indications to the operator.
Synchronizing panel is mostly used in Power plants, Industries, or in any place where multiple power sources are used to ensure continuity of power supply.
