DTTS DISTRIBUTION TRANSFORMER TEST SYSTEM www.haefely.com

DISTRIBUTION TRANSFORMERS: ROUTINE TESTING MADE EASY Distribution transformers are “mass production equipment”; high testing-throughput is a must without compromising quality. Our 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. Our Distribution Transformer Test System (DTTS) has been designed with these requirements in mind, as a multifunctional tool for testing distribution transformers. All supported tests are performed in conformity...

Distribution Transformer Test System BLOCK DIAGRAM DTTS MASTER PC RESISTANCE APPLIED VOLTAGE INDUCED VOLTAGE TURNS RATIO LOAD LOSS INSULATION RESISTANCE (PARTIAL DISCHARGE) State of the art frequency converter The highest accuracy and the only completely calibrated and certified measurement system The lowest system-noise level allowing highly sensitive Partial Discharge measurements Powerful operating software with intuitive interface and automated test sequences

It is unique in the market, integrating all routine tests within one compact system. The DTTS is a complete turnkey solution assuring the customer 100% satisfaction. The DTTS is capable of testing both dry type and oil immersed distribution transformers. CERTIFIED CALIBRATION NO ACTIVE PARTS, NO MAINTENANCE REQUIRED AUTO TEST PROCEDURE GUARANTEED AFTER SALES SERVICE Low voltage capacitor bank switched automatically, reduces mains power consumption.
