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.

Electrical testing on rail systems is essential for safety and reliability
Standard ohmmeters are inadequate to accurately determine the resistance of high-current connections and a digital low resistance ohmmeter should be used. Modern TDRs can locate able faults at distances up to 20 km from the point at which the instrument is connected and some types feature dual channel operation, which allows faults between cables to be rapidly localised.

Electric and hybrid vehicles need a special testing regime
Insulation test instruments for use in garages on electric vehicles need to be both physically tough because of the environment in which they are used, and to provide accurate diagnostic information. Wireless data communication ensures that faults and critical trending information are diagnosed rapidly.

Earth leakage clamp applications
An earth leakage clamp is a pocket-size clamp meter designed to measure AC earth leakage currents. They enable earth leakage faults to be detected and located without having to isolate and disconnect circuit wiring. In addition, most of these clamps are capable of performing AC current tests like any normal clamp meter. This paper looks at their applications in detail.
