Electrical Fault Finding Techniques

In order to do it properly you need to be able to use some electrical fault finding techniques that will allow you to discover the problem and solve it.

Electrical fault finding techniques.

Essential items in the fault finding toolbox two even better than one they allow you to measure both voltage and current. If you are convinced that the earth is touching the phase or vice versa or the ph is touching the n prior to the load then you would carry out an ir test at 500 volts dc between the ph e or ph n. Finding electrical faults you will need basic knowledge of electrical faults identification in addition to electrical diagrams generally an electrical circuit is made of electrical components like lights pumps fans and motors switches fuses relays circuit breakers and fusible links. Principles of systematic fault diagnosis diagnosis of faults requires a logical and disciplined approach.

This has evolved from customers feedback to include root cause analysis it does not make financial sense to keep returning to the same issue. Discuss fault finding techniques. To help technicians get to the cause of a fault faster mcp has developed a course focusing on a logical approach to fault finding. Electrical fault finding techniques.

Electrical fault finding techniques when you need to troubleshoot electrical equipment you will either need to replace the faulty component or replace the defective equipment completely. 1 of 2 go to page. You may at times be fortunate and have a schematic electrical drawing and at times there will be nothing. Capacitors can store electrical charge and give electric shocks.

Fault location techniques can be broadly divided into terminal methods which use voltages and currents measured at the ends of the cable and tracer methods which require inspection along the length of the cable. Although they offer this for both ac and dc usually dc measurement is sufficient. If you have the wiring diagram fault finding is. Locating faults in a cable system can be done either with the circuit de energized or in some cases with the circuit under power.

A typical electrical circuit consists of an electrical component pump light motors fan etc any switches relays fuses fusible links or circuit breakers related to that component and the wiring and connectors which link the component to both the battery and the chassis which is connected back to the battery to complete the circuit. These principles apply in all disciplines regardless of whether they are civil electrical mechanical etc. In this section we look at the general principles of fault finding through the application of diagnostic reporting.
