What is inertia constant of generator?

The inertia constant of a generator is a measure of how much kinetic energy it can provide to the power system during sudden changes in frequency. It is typically expressed in seconds and is a key parameter for determining the system's ability to maintain stability during disturbances. Generators with higher inertia constants can better withstand sudden changes in power demand or system disturbances.

How Capacitor functions as PF Corrector?

A capacitor functions as a power factor corrector by storing and releasing electrical energy to offset the reactive power drawn by inductive loads in a power system. When connected in parallel with the load, the capacitor supplies reactive power, improving the power factor and reducing overall system losses. This helps to improve efficiency, reduce voltage drops, and maximize the utilization of power distribution equipment.

Will upgrading to a 400amp from 200amp main service circuit breaker cure power drops NOT outages just drops in power amperage I currently have 200amp main service and am considering upgrading to 400?

Increasing the ampacity of your service will not cure power drops. If your main breaker has not tripped then your connected load is under 200 amps. The power drops are the responsibility of your utility company. They are required to keep the voltage within a 10% tolerance. When asked some utility companies will connect a recording volt meter to your line to check your claim of low voltage. Call them. Log the time when the power drops over a week. If they will not monitor your line give them the list of the power drops that you recorded as this may help them. You are probably at the end of the line and connections up stream are probably the cause of your power fluctuations.
