TRANSFER SWITCH WITH MAXIMUM POWER LEARN FUNCTION

摘要

Aspects of the present disclosure involve systems, devices, methods, and the like, for a transfer switch of a power system incorporating a self-powered electronic meter that provides a learn function to determine the maximum amount of power an attached generator can provide, and adjust a power meter display associated with the switch accordingly so that the indicator of the display may be used for any size generator and display the full range of the generator. The learning function is activated and a user turn on devices and loads in the load center until the generator stalls. A microcontroller records the max generator power that was measured before the generator stalled and save it to non-volatile memory as the new 100% setting for that particular generator connected to the transfer switch.

主权项

1. A manual transfer switch, the switch comprising:
a switch comprising a first position that provides power from a first power source to a load center in electrical communication with the manual transfer switch and a second position that provides power from a second power source to the load center; a power meter for displaying an indication of a power level provided to the load center; and a control circuit comprising a processor and at least one memory device, the processor executing one or more instructions stored in the at least one memory device, the instructions causing the control circuit to:
monitor the second power source for an overload condition of the second power source;detect the overload condition of the second power source;store a maximum power level of the second power source in the at least one memory device, the maximum power level of the second power source associated with the overload condition of the second power source; andcalculate a percentage of the maximum power provided to the load center from the second power source, the percentage of the maximum power comprising a current power provided by the second power source to the load center divided by the maximum power level of the second power source; wherein the indication of the power level of the second power source provided to the load center is the calculated percentage of maximum power.
