Test Electrical Equipment (Transformers, Cables, Circuit Breakers, Meters)

This program is aimed at all personnel who are involved in plant maintenance including operators, maintenance technicians, craftsmen and management. Our Objective is to present techniques used in modern plants to measure on an ongoing basis, the rate of deterioration of equipment, analysis and interpretation of such information, and the resultant implementation of predictive maintenance.
