Strategies for Accurate Vibro-Acoustic Monitoring of OLTCs

Vibro-acoustic diagnostics have emerged as a rapid and non-invasive method to monitor and assess the health of On Load Tap Changers (OLTCs) in electrical power systems. This technology detects and analyzes the vibrations and sound patterns generated by OLTCs during operation, helping to identify...

Safe Electrical Maintenance Checklist

Reduce the risk of arc flash hazards with CSA Z462 BY ROBERT BURGESS, Lineman’s Testing Laboratories Safe electrical maintenance practices and on-going personnel training can minimize the likelihood of electrical injuries and fatalities due to electrical shock, electrocution, arc flash and arc...

CSA Z462 and CSA Z463: A Powerful Combination

I recently viewed a destroyed 600-volt electrical panel board that had exploded when an operator reset an 800-ampere (A) breaker. His leather-palmed gloves had synthetic backs that ignited and seriously burned the back of his hands. His flame-resistant (FR) shirt was untucked and he was burned on...

Understanding the DC Overpotential Test

The 411 on DC testing of low-voltage circuit breakers BY JIM WHITE, Shermco Industries, Inc. The direct current (DC) overpotential test is one of the basic tests conducted to ensure an insulation system has adequate insulation life to make it to the next scheduled maintenance interval. While not...

Thermography Best Practices

Providing continuous electrical high quality power is an ongoing challenge. Many industries must have continuous, uninterrupted quality power to ensure production levels are maintained and the integrity of their computer systems are at their peak levels. Furthermore, many buildings such as hospitals must have continuous, reliable power to ensure life-critical devices are running in operating and intensive care rooms. This formidable task can be partially achieved with proper maintenance practices.

There are many maintenance tools,...
