New RESA Power Sample Guard Provides Safe Sampling of Transformer Oil from Energized Padmount Transformers

Safely access transformer oil and nitrogen service lines without Arc Flash


RESA Power, LLC, a market leader in life extension solutions for power distribution & control equipment has introduced the Sample Guard enclosure for cabinet style transformers. Sample Guard enables safe access to oil sample and nitrogen service lines by relocating them to an enclosure mounted outside the transformer. Technicians can pull oil samples and service the nitrogen blanket with zero risk of Arc Flash.

“Our new Sample Guard product allows technicians to safely collect samples without having to power down the transformer. This helps ensure the protection of the technician while also reducing downtime,” said Mark Angus, COO West Region for RESA Power. “The National Fire Protection Association (NFPA) states that 2,000 people are treated annually at burn centers for Arc Flash injuries and five to ten arc explosions occur in electrical equipment in the U.S. every day.” Mark added, “Installation of our Sample Guard product will help reduce the risk of these types of injuries by providing a safe way to sample an energized padmount transformer.”

Sample Guard enclosures are easy to mount and arrive with the hardware necessary for installation. The exterior has a NEMA-rated powder coated finish that will last for years in various types of weather. Lead time for the enclosures is two weeks.
