SPTTS series of transformer test sets make it easy to conduct IEC / IEEE mandated routine and type tests on Small Power transformers. SPTTS is a modular, highly versatile system for testing Small and Medium Power transformers. Control software mimics the test procedures typically followed by test operators around the world and makes it easy for a new operator to adapt to the system. Control is SIL 3 rated. System is completed by well built Frequency converter, Step Up Transformer, Partial Discharge filters & Loss Measurement System.
