Relay protection devices have some functions
Protection relays have a crucial role in maintaining the safety, reliability, and integrity of electric networks. They recognize problems before they become serious. This decreases the frequency of operation in production, avoids equipment damage, and guarantees a continuous power. The rectangular devices are test connection blocks, used for testing and isolation of instrument transformer circuits. In electrical engineering, a protective relay is a relay device designed to trip a circuit breaker when a fault is detected. Types of Protective Relays: Protective relays are categorized by their mechanism (electromagnetic, static, mechanical) and function. A protective relay is an intelligent device that senses abnormal electrical conditions, such as overcurrent, under-voltage, or frequency deviations.

Principle of High Voltage Motor Relay Protection
Electromagnetic Relays: Working on the principle of electromagnetic induction, these relays are typically used for phase failure and under/over voltage conditions. They act quickly to isolate the motor and protect it. High Voltage Induction Motors: These motors are preferred for high power applications (above 250HP) due to their reduced operating. Motor Protection relays are used to protect the higher HP high voltage induction motor. Once the temperature crosses a certain threshold, it trips the circuit. It is suitable for critical equipment like servo and high-voltage.
