In the past, measuring the capacitance and dissipation factor of a test specimen at manufacturing facilities was carried out using high voltage sources and Schering bridges. Today, automatic-balancing bridges provide an innovative solution with very high...

Testing transformers at non-traditional frequencies can provide invaluable diagnostic information. This has led to the development of a whole range of novel test techniques. Because “frequency” appears in their title this has led to confusion...

Today's power distribution grid is changing rapidly and these changes can be expected to have an impact on power quality, which is the concept of powering sensitive equipment in a manner that is suitable to the operation of that equipment.

Power cable faults are the bane of every network operator’s life. Faults on recently installed cables are particularly exasperating, as a reasonable expectation is that new cables will operate reliably.
