Electrical apparatus and equipment testing

There are very many circumstances in which electrical apparatus and equipment need to be tested some examples are  [Pg.314]

The risks of electrical injury during testing can be inherently high because conductors energised at dangerous voltages are often exposed to [Pg.314]

In those situations where testing must be done with the conductors live, the most important requirement is that the tester is protected against direct contact with those conductors energised at dangerous potentials. There are two main ways in which this can be achieved  [Pg.315]

Live testing of equipment, apparatus and installations is a eommon eause of electrical injury and frequently requires eareful consideration and planning of the precautions needed to reduee the risks to an acceptable level. In all cases it is essential that the person earrying out the test is competent, having received adequate training and instruction on the risks and the technique to be used to avoid injury. There should always be a sufficiently comprehensive risk assessment carried out, with a clear and unambiguous explanation of the safety precautions. The main techniques that can be employed, most often in combinations, are  [Pg.317]

The use of isolating transformers, coupled with the removal of conducting paths to earth in the vicinity of the test area. [Pg.317]
