To meet such high current and voltage requirements without exceeding the power and temperature thresholds, power relays are used. One of the factors working against them is the pressures that they develop when in operation. Higher voltages and higher current applications. Reversing and non-reversing (NEMA or IEC) Principles of Electric Circuits: Conventional Current. The main purpose of this starting relay is to bring in an additional electrical circuit, giving the motor the extra torque it requires to start. The relation between power, current, and resistance is shown by the expression below, Where, The current relay and the potential relay both are used to drop the starting circuit. It generally uses two circuits - A control circuit and a power circuit.The control circuit regulates the flow of power and performs the basic switching operation using a small amount of current which can in turn be used to control a circuit with a high amount of current. Smaller. Hence, it can be said that the relay will only operate when the impedance of the line becomes less than predetermined impedance (voltage/current).
