Product details

DEIF's OPM-1 is an advanced combined differential protection and short circuit protection relay designed for internal short circuit (leakage current) protection in generators. This relay combines differential protection and short circuit protection, which can accurately and quickly detect and isolate internal faults of the generator to ensure the safe and stable operation of the power system.

Differential protection is a protection method based on current comparison, by comparing the current difference between the two sides of the generator to determine whether there is a fault. When an internal short circuit occurs, the current on the fault side increases, while the current on the non-fault side remains unchanged or decreases, resulting in a current difference. The OPM-1 is able to accurately measure these current differences and quickly shut off the relevant circuits when a fault is detected, preventing the fault from expanding.

At the same time, the OPM-1 also has short-circuit protection. When the generator short-circuit fault occurs, the short-circuit current will increase sharply, which may cause serious damage to the generator and power system. The OPM-1 is able to monitor current changes in real time and quickly cut power if a short circuit fault is detected, protecting the generator from damage.

The OPM-1 is designed with a wide range of application scenarios and fault types in mind for high reliability and sensitivity. It adopts advanced algorithm and circuit design, which can accurately identify various failure modes and take corresponding protective measures. In addition, OPM-1 is easy to configure and maintain, and users can flexibly set and adjust according to actual requirements.

Overall, DEIF's OPM-1 is a powerful, high-performance generator protection relay that provides comprehensive fault detection and protection capabilities for power systems.
