| Abstract: | The paper mainly analyzes the cause of the circuit breaker tripping fault which is caused by the burned contact of the exit relay in master transformer protection mechanism as a result of defective design of the control loop in 35 kV station.It gives a detailed investigation and analysis of the cause of the trouble and puts forward the improvement measures of control loop.The trip relay test verifies the feasibility and ef-fectiveness of such improvement,with matters called for attention in design,construction and commissioning of the control loop. |
