Diverse industries form the foundation of Indonesia’s thriving economy. From manufacturing to real estate, a long list of industries contributes significantly to its prosperity. In this rapidly growing industrial landscape, even a single downtime event can cause millions in losses. What’s often to blame in situations like this? It can be a lack of proper relay coordination. A well-designed and implemented protection strategy can reduce these nuisance trippings and ensure operational continuity.

The engineering technique used to analyze and identify the settings and coordination of these protective devices, like relays, switchgears, and circuit breakers, is called a relay coordination study. When these protective devices are working in a time-based logical sequence, any faults in the system can be isolated without disrupting the entire system. They work as follows:
In Indonesia, the root cause of nuisance tripping and defective relay coordination can be summarized as:
A professional relay coordination study includes the following:
