Predictive diagnostic testing of electrical apparatus including transformers
Electric apparatus sometimes fails because of insulation deterioration. A proactive approach using Tan delta/power factor diagnostic testing is the key to monitoring the integrity of the insulation system and preventing or at least anticipating such failures. Understanding the impact of these parameters will help in obtaining accurate measurements that can be relied upon in the decision making process.

Power factor testing of bushings
Bushings provide an insulated path for energised conductors to enter grounded electrical power apparatus. They are a critical part of the electrical system that transforms and switches AC voltages ranging from a few hundred volts to several thousand volts. This paper includes a glossary of various terms in relation to bushings and goes into detail about the different methods of testing them.
