Injection motor solid state energy saver is a electronic unit .it comes along with current transformer. The current transformer is to designed and match the each capacity of full load current. The current transformer sensing line current is below 50 percentage of full load current.the energy saver unit motor is to operate in star mode and till the line current rises to 48 percentage of full load . When the sensing current reaches set current of 48 percentage i.e line current of full load injuction motor energy saver unit to operate ,the motor in delta.
