Guide to transformer winding resistance measurements
Measuring a transformer's DC resistance from one external terminal to another can reveal a great deal of information about the transformer. In addition to the obvious faulted winding (i.e., an open winding or shorted turn), more subtle problems can be detected.

Testing electric vehicle supply equipment
Most installations require an additional connection to ground at the charging point, so that there is still a form of protection under fault conditions. This connection would be made by an earth spike/electrode driven into the ground.

Using a TDR to find cable faults without applying a high voltage
Although you will still need a combination of test instruments including an insulation test set, in the right circumstances, a TDR can sometimes locate cable faults without the need to apply a high voltage to the cable.

The batteries that radar UPS systems depend on need regular testing to ensure that the skies stay safe
Batteries play a crucial role in ensuring that air traffic control systems around the world can continue to operate reliably and safely, even if there is a failure of the mains supply at the radar stations on which they rely. It is imperative, therefore, that those batteries should be maintained in good condition, with potential problems detected and remedied before they can develop into outright failures.
