DTTS - Transformer Test System

Distribution transformers are "mass production equipment"; high testing-throughout is a must without compromising quality. Haefely's DTTS aims at a highly automated test procedure using well-prepared sequences and minimal manual intervention to keep the test duration of a single transformer as short as possible and to avoid human errors

Their Distribution Transformer Test Systems (DTTS) has been designed with these requirements in mind, as a multifunctional tool for testing distribution transformers. All supported tests are performed in conformity with IEC, IEEE/ANSI and GOST. Focus is on flexibility and maximum testing through-put, while ensuring quality, continuing Haefely's philosophy of more than 100 years.
