| Abstract: | Air Circuit Breaker is an upstream device to make and break the current even in case of any abnormality in system. ACB can sense the abnormal system conditions like short circuit, earth fault and overload etc. Also in some cases like high inrush current may cause drop in system voltage and to sense this fault Under Voltage Release is used. UVR trips circuit breaker if voltage falls between 35 to 70 percentage of its rated voltage. Current UVR can operate only on 1-Phase under voltage fault. In order to sense under voltage fault in 3-Phase system, 3-Phase UVR has to be developed. Additionally UVR has time delay controller which trips the breaker after pre-defined time delay.To provide the solution for three phase voltage dip sensing 3-Phase UVR, 3-Phase controller has to be developed. |
