NEMA pilot duty ratings Course Hero is not sponsored or endorsed by any college or university. The difference between relays and time delay relays is when the output contacts open & close: on a control relay, it happens when voltage is applied and removed from the coil; on time delay relays, the contacts can open or close before or after some time delay. Disadvantages of Current Differential Relay : Under heavy flow of currents, the accuracy of the relay gets affected due to the capacitance of the pilot cable. On the secondary side is our load connected between the other terminals of the relay and powered by a 120V AC source. Potential relays (relays are used, as a rule, high-torque capacitor-start the engines.
