SE-325D is a type of protection relay system designed by GE. With its advanced features and versatile functionality, it can be used in a variety of applications and settings. It is a multi-function protection relay which is mainly used to provide protection for power system equipment against such faults as electrical overcurrent, undercurrent, short-circuit, ground-fault, overload and others. It has a rapid response time and is designed to provide reliable protection for industrial, commercial, and residential customers.

SE-325D\'s main features include over-/under-voltage protection, three phase or phase to ground fault protection, under-/over-current protection, accommodation for two time-delay settings, back-up protection, adjustable time pick-up, earth-fault protection and breaker trip signal.

The working principle of SE-325D is based on the use of a specially designed microprocessor. This microprocessor is programmed to detect any power or technical fault and to immediately send a message or signal to the main control station. The signal will then inform the control station about the type of fault and its location. Based on this information, the control station can then take the necessary action to protect the system from the fault.

SE-325D can be used in a variety of applications and settings. It is particularly suitable for use in large-scale power grid systems such as those used for transmission and distribution. It is also suitable for use in commercial and residential power systems and for protection of small-scale high voltage systems. Additionally, it is an ideal protection solution for high voltage industrial installations such as transformer stations and substations.

SE-325D is highly reliable and easy to maintain. Its microprocessor-based design is durable and allows access to advanced features such as time delay settings. Additionally, it features an adjustable time pick-up for high-precision fault detection. Moreover, it is also equipped with a breaker trip signal, which ensures that the correct corrective action is taken when a fault is detected.

In conclusion, SE-325D is a reliable and versatile protection relay system, designed by GE to protect industrial, commercial and residential power systems from faults. Its advanced features and fast response times allow it to quickly detect and respond to any power or technical fault, thereby ensuring the reliable and safe operation of the system.
