Monitoring and Protection System for Overvoltage, Undervoltage and Unbalance Voltage

The biggest loss in the industry that caused to experience financial losses should have been target of achieving 90% - 100% production was a decrease up 40%, due machines not running excessive loads used resulting overvoltage disturbances, voltage drops or unbalanced voltages. To overcome monitoring tool and protection system are needed with method can cut off load automatically when disturbance occurs, namely by using contactor as breaker from source then controlled. microcontroller utilizes relays sensors. So results obtained manufacture tools refer SPLN NEMA disturbances ranging 399V 413V, drop occurs at 320V 328V, while test is balanced R phase which different S T phase, percentage unbalance 3%, will it hoped carried out return achievement industry.
