Troubleshoot general steps - to determine the point of failure

According to the failure phenomenon,combined with the principle of equipment and control characteristics analysis and judgment,determine the scope of the fault occurred in what,electrical fault or mechanical electrical motor failure,is a dc circuit or ac circuit,main circuit and control circuit or auxiliary circuit,power supply part or parameter adjustment www.facebook.com/guohong.trading is caused by the inappropriate,man-made or randomness and so on,gradually narrowing the scope of the fault,until find the point of failure.If lack of system of diagnosis information,you need the whole ac induction motor equipment maintenance personnel correctly or control system is divided into several pieces,then check the parts of the input and output is normal.When determining a certain part,and then to focus on the part of the internal problems,find out diesel generators prices the point of failure.Under the condition of ensure the safety of equipment,can pass some test method to determine the fault position.Electricity to test,for example,or to make a relay action,etc.,to find and determine fault location.
