Types of Products in the Category Protection Relays

Protection relays are designed to monitor electrical systems and react when specific parameters are exceeded, thus preventing damage to equipment. In the BaltElec store, we offer a variety of protection relays, each catering to a different aspect of system protection. Below are the main types of protection relays we offer:

Overcurrent Protection Relays
Overcurrent protection relays are designed to protect circuits from damage caused by excessive current. These relays measure the current in the circuit and activate when it exceeds a predetermined level. There are two main types of overcurrent protection:

Instantaneous overcurrent relays – respond immediately to an overcurrent event.
Time-delay overcurrent relays – allow a delay before they trip the circuit, offering protection against temporary overloads.

Overvoltage and Undervoltage Protection Relays
These relays protect electrical equipment from damage caused by voltage fluctuations. An overvoltage condition occurs when the voltage exceeds the normal operating level, while an undervoltage condition occurs when the voltage falls below a specified limit. Both types of protection are essential for sensitive equipment that requires a stable supply voltage.

Differential Protection Relays
Differential protection relays are used to detect differences in current between two or more points in an electrical circuit. If a difference occurs, the relay will trip the circuit to prevent damage. These are commonly used for transformer protection and other critical components of electrical systems.

Earth Fault Protection Relays
Earth fault protection relays are designed to detect ground faults in an electrical system. These faults occur when a current leaks to earth due to insulation failure or short-circuit conditions. Earth fault relays help prevent fires and other hazardous conditions caused by electrical leakage.

Thermal Overload Protection Relays
These relays protect motors and other devices from overheating due to prolonged overloading. They typically operate by sensing the temperature increase in the system and triggering an alarm or shutting down the system to prevent damage.

Phase Loss and Phase Sequence Relays
Phase loss and sequence relays ensure that motors and other rotating machinery operate with the correct phase sequence and voltage. They protect systems from malfunctioning in the case of missing phases or incorrect phase sequence, which could lead to severe damage.
