Transformer Testing

Transformer Testing

RTRC Limited provides advanced testing facilities for various types of transformers, including Power Distribution Transformers, Dry-type power transformers, Outdoor/indoor type oil immersed distribution transformers up to and including up to 2.5 MVA, 33 kVE.

Transformer testing is a vital process within electrical distribution systems to ensure that transformers operate reliably, safely, and efficiently. Transformers are central to regulating voltage levels across distribution networks, stepping up or down voltage to maintain consistent power flow and minimize losses. Proper testing helps identify potential issues early, assess the condition and performance of the transformer, and verify compliance with safety and efficiency standards.

We also perform special tests on transformers according to customer requirements to provide valuable information for operation and maintenance.

“Energy loss in transformers is indeed a significant concern, as it directly affects efficiency, operational costs, and environmental sustainability. Transformer testing is a critical diagnostic tool for identifying and mitigating these losses”.
