The NDB-DOC-3 is a specialized testing instrument designed for assessing distribution transformers within the range of 5 kVA to 3 MVA. This device can accurately diagnose the existence of short or open circuits in both the primary and secondary windings of transformers, a critical aspect of ensuring transformer reliability and safety. Its design allows usage without the need to disconnect the secondary windings, thus optimizing operational time. This functionality is particularly beneficial in maintaining transformers in energised conditions, thereby avoiding unnecessary downtime. The test results can pinpoint issues that may lead to transformer failures, making it an invaluable tool for electrical engineers and technicians working in the maintenance of electrical distribution networks. With a robust build, it comes with various accessories including replacement test leads and transportation cases, enhancing its usability and protection during transit.
