Wireless Measurement Systems

Conquering challenges with wireless measurement systems BY COLIN PLASTOW, Fluke Electronics Any type of manufacturing or industrial environment presents a number of challenges when taking measurements. Whether you need to check performance over time or run spot checks, there are many situations...

Thermography 101

Thermography used to be expensive, difficult, and primarily used by large industrial facilities and the military. These days, it has become much more affordable, easier to use, and more broadly applied. A thermal imager works by producing thermal (heat) pictures of the equipment. Electrical...

Vacuum Interrupter Testing

Predicting remainder of field life finally becomes easier BY FINLEY LEDBETTER, Group CBS Vacuum interrupters (VIs) have widely replaced older air-magnetic and oil interrupters for circuit breakers rated at one kilovolt (kV) or higher. These devices offer up to 10 times the expected lifetime than...

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...

Vibro-Acoustic Diagnostics for OLTCs

On-load tap changers (OLTCs) are crucial components within power transformers, enabling voltage regulation while the transformer remains energized. Maintaining the health of OLTCs is essential for ensuring grid reliability and efficient power delivery. Traditionally, diagnosing potential problems in OLTCs relied on intrusive methods like offline inspections or taking oil samples for analysis. These techniques require taking the transformer out of service, leading to downtime and increased maintenance costs. Vibro-Acoustic (VAM) technology offers a promising alternative,...
