The Voltage of the power supply system is rated at its designed value. If this voltage goes down predetermined set value a under voltage relay can sense the change and then trips off the circuit.

Cause of single phase capacitor start motor burning?
mainly due to undervoltage.
What is thermocouple cable?
The thermocouple is an sesnsing device , when the temperature increases it increases the voltage , that voltage is used for tripping purpose
Will multiple tripping of a circuit breaker damage the circuit breaker?
You don't specify whether you mean low-voltage circuit breakers, such as MCBs (miniature circuit breakers) or high-voltage circuit breakers. In either case, repeated tripping under fault conditions causes arcing which damages the main contacts of the circuit breakers. For this reason, high-voltage circuit breakers are taken out of service after a specified number of tripping operations, so that the contacts can be maintained or, if necessary, replaced. MCB contacts are inaccessible, and the MCB may eventually require replacing.
Why does your protective device keep tripping out?
Because something is wrong. Check for shorts and, if it is a GFCI, also check for ground faults and leakages. It is also possible, in the case of a GFCI, that an inappropriate load, such as a computer monitor or UPS, is connected. These devices pull transient power to ground and will trip a GFCI. Do not ignore the situation. The protective device is tripping for a reason.
What is cascade tripping and how it happens?
cascade tripping or failure is a failure in a system of interconnected parts in which the failure of part can trigger the failure of successive part.it means that failure in one part of system may quickly spread into entire system . cascade tripping occurs for several reason -when component of grid is over stressed -generator shut down due to any reason -if transmission line has too much current following on it, and it will heat up and conductor fails -when tree are close to transmission line ,electric current from line will produce arc ,and circuit breaker disconnect line . -natural climate like earthquake ,heavy rain etc ,in which pole are fall down.
What is prolonged undervoltage?

What is a 27 relay?
undervoltage relay
Where you use undervoltage protection?
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.
