Default Re: Swan kettle element.

Here's how to test a kettle element. For clarity the element is shown removed from the kettle, but it can be tested in situ. Note that the cut-out is set as shown by the rectangular brass pin being pushed in. If the cut out has operated push the pin in to reset it.

In the first picture the element is shown being tested for continuity. The reading of 62.7 ohms is consistent with a 1kW element designed for a 250VAC supply.

The second picture shows the element being tested for insulation breakdown. Make sure that the clip attached to the element cuts through any fur. The reading is infinite which is correct.

NOTE THAT THIS TEST IS NOT FOOLPROOF AS IT IS BEING CARRIED OUT AT LOW VOLTAGE.

An infinite reading indicates that the element MAY be good.

Any other reading indicates that the element IS bad.

The third picture shows insulation breakdown being checked at 500V using a "megger" or in this case a Metrohm. The infinite reading indicates that the element is good.
