Master electrical troubleshooting methods

Faults exclusion is an important work of maintenance personnel,to eliminate the fault,must know the cause of the failure,more important is can theoretically analysis,solve the fault occurred,should have certain professional theory knowledge,to permanent magnet generator master the methods of troubleshooting.(a) resistance test method:resistance test method is a commonly used method of measurement.Usually refers to the resistance using the multimeter,measure motor,lines,touch the top is in line with permanent magnet motors for sale the use of nominal value,and whether a method of on and off,or use the megohmmeter measuring phase phase,phase to the insulation resistance between the and so on.

Measurement,pay attention to the selection range and the accuracy of the check table,used by general resistance method is used to measure the general practice is to choose low first,when the circuit being measured should be paid more attention to whether there is a loop,and it is strictly prohibited to charged measurement.(2) voltage test method:test method is the use of multimeter corresponding voltage 12v motor profile,a method of measuring circuit voltage value.Usually measurement,sometimes measuring power source voltage,load,sometimes also measure the open circuit voltage,to determine the line is normal.Table should be paid attention to when measuring gear,choose the appropriate range,general measure is unknown or when the open circuit voltage usually choose ac voltage of the electricalmotor1.blogspot.com high-grade,to ensure that not in operation under high low voltage range,in order to avoid damage to the table.To measure dc at the same time,pay attention to the positive and negative polarity.
