DBKC-2008 Transformer OLTC Tester

Product Introduction

On-load tap changer ( OLTC) is the only moving part which connected to the transformer circuit and the detection of OLTC is being attached great importance. According to Procedures for the Handover and Prevention of Electrical Power Equipment, OLTC’s action sequence and change-over time are required items to be detected. DBKC-2008 Transformer OLTC Tester is produced by our company to measure transition waveform, transition time, transient resistance and three-phase synchronization.

DBKC-2008 Transformer OLTC Tester is smart with English-interface. It’s light-weight and easy to operate and carry to the site. It’s the ideal testing equipment for maintenance of power supply units and transformer manufacturers.
