This instrument provides the most direct method for assessing whether transformer windings have deformed after being subjected to short-circuit current impacts or mechanical shocks during transportation and installation. It plays a crucial role in determining whether a transformer can be put into service and serves as a key criterion for deciding if disassembly inspection is required.
Our independently developed next-generation transformer parameter measurement instrument is designed for low-voltage short-circuit impedance measurements on 35kV and higher-voltage main transformers under both field and laboratory conditions. Featuring a compact design and powerful functionality, it incorporates a built-in 2000W adjustable power supply and utilizes advanced A/D synchronous AC sampling and digital signal processing technology for highly accurate measurement data.
