Product Description
Product Description
DTBK tester is designed to test the on-load tap-changer (OLTC) of power transformer and special transformer. It is capable to measure the OLTC's transient time, transient wave, transient resistance, 3-pH synchronism, etc. The user can connect the tester to OLTC directly or bushings and neutral of transformer to do test process on site.
Functions & Features:
More parameters measurementCapable to recognize open circuit during tap-changing, and measure the transient time, transient wave, transient resistance, 3-pH synchronism, etc.
Oscilloscope Function3-channel to record 3-phase transient process including the time at transition point, without the effect of weather.
Measurement result analysisThe user can analyze the transient waveform to know well the transient process including the changes of every parameter during tap-changing. The transient wave can be printed and saved for later comparison and analysis.
Can save all test data and print test report.
Large LCD, menu operation, and operation prompt facilitate using very easy.
Strong anti-interference abilityAluminum alloy case, built-in power noise filter and anti-interference circuit ensure working reliably on site.
