Transformer Multifunctional Tester
Transformers are the core equipment of power systems, and their long-term reliable operation is critical to overall grid stability. Efficiency grading, DC resistance, voltage ratio group, and insulation resistance tests are mandatory for transformer out-of-service maintenance. Traditional testing requires four separate instruments, which are bulky to carry and involve repeated disconnection and reconnection of specialized test leads—wasting substantial manpower, materials, and working hours. Wrindu has innovatively launched a four-in-one distribution transformer test system that integrates DC resistance, voltage ratio, insulation resistance, and efficiency grading into one compact unit. Powered by a high-capacity lithium battery, it supports single-wiring, multi-test operation, eliminating frequent lead changes and drastically boosting testing efficiency and convenience.
