Undervoltage protection is provided for A circuit bars,motors, generators, Transformers, rectifiers, etc.. Such protection is given by means of undervoltage relay. Undervoltage relay are necessary for voltage control and reactive power control of network buses and load buses. These type of relays have inverse time characteristics and their operating time reduces twith the reduction in operating voltage.

When use undervoltage release?

Under voltage protection (release?) is used in industry. If there was a power failure and a piece of equipment was running when the failure occurred for safety reasons the machinery should not start up on its own when the power returns back on. With under voltage protection the operator restarts the machinery after checking that there is no danger to anyone and the machine is clear to start. To obtain this safety feature an electrical contactor is used in conjunction with remote stop - start buttons located at the machine the operator is working.

What are the disadvantages of a parallel?

What is arguably the major disadvantage of a parallel circuit is that as you add more and more things in parallel, the current draw on the source goes up and up and up. If the source cannot supply the current that is "demanded" by the devices all strapped across the so-called "rails" of the circuit, the voltage will (must!) decrease. This could be very bad, as some devices, notably motors, don't like to run at low voltage and can actually be damaged if voltage sags too much and they don't have undervoltage protection. Fortunately, we have a pretty good power grid in many places, and this isn't a problem. Additionally, many devices have undervoltage protection built in, and they'll "trip" and shut down if voltages sag to a preset threshold.
