Rancang Bangun Elektronik Motor Relay sebagai Proteksi Berbagai Gangguan Motor Listrik

The protection system against disturbances in induction motors has an important role industry. In general, electrical installations only uses MCB (Miniature Circuit Breaker) and fuses which can protect overcurrent short circuits there are still many kinds of that have not been covered it even though along with technological developments electronic devices created. purpose this final project is to plan manufacture motor relays over load, phase loss, reverse, unbalance, circuit, ground fault, locked rotor disturbances. AVR microcontroller used as a controller for all systems detecting Where the current setting range trip time programmed using C language operated keypad displayed on LCD. As voltage sensing transformers transformers. takes signal from differential amplifier forwards zero crossing, trigger X-or. Testing accuracy relay carried out each fault. data obtained shows be precision analog controller. This because good features supported by adequate processor speed use kind application.
