amperage measurement coils
Hi,
I am also not clear about the term inrush current, unless due to activation of the plunger, the effective inductance increases.
Any how, you can measure the Operate and release current by applying a variable AC voltage source in series with an AC current meter to the solenoid. For AC coils it is the inductance that matters more than the DC resistance that you measure with an Ohm meter. The resistance gets added vectorially to the AC reactance of the inductance.
By the way, why do you want to increase the inrush current ? Obviously if the plunger is moved away, you need more force and therefore more current to operate it.
