Sample Guard Transformer Enclosure

Reliable and Safe

Many industrial companies operate non-stop around the clock, making it difficult for maintenance technicians to provide safe access to equipment for transformer repair. RESA Power can support the safety of your technicians with a Sample Guard enclosure for cabinet-style transformers. This allows for safe access to perform transformer oil sampling and nitrogen service lines by relocating them to an enclosure mounted outside the transformer, saving the technicians from having to power down the transformer or remove it from service and disrupt operations.

RESA Power produces fully customizable remote external sampling devices and systems that allow technicians to safely collect oil samples and service the nitrogen blanket with zero risk of Arc Flash.

Prevent Arc Flash Injuries

Every day in the US, five to ten arc flash explosions occur involving electrical equipment. Arc Flashes can be caused by several factors including dust, condensation, accidental touching, material failure, corrosion and faulty installation, among others. The severity of an Arc Flash injury can be intensified by the proximity of the worker to the hazard. (link to the page with Arc Flash training)

The National Fire Protection Association (NFPA) states that 2,000 people are treated annually at burn centers for arc flash injuries. Injuries can vary from minor burns from fire to blindness, hearing loss, nerve damage, third degree burns and in some cases, death. Long-term and extended medical care are often required, resulting in costly medical bills and fees.

Avoid these types of injuries by installing our Sample Guard product, a safe way to sample an energized padmount transformer.
