Zensol introduces a new instrument, the TAP-4 totally dedicated to Vibro-Acoustic measurements on On-Load Tap Changers.

Faults associated to On-Load Tap Changers are at the origin of up to 40% of the transformer failures.

This new instrument allows the maintenance crew to detect most of common OLTC malfunctions as contact wear, arcing in diverter, arcing in selector, synchronism problem, drive mechanism problem, brake failure etc ...

The OpenZen software drives the TAP-4 from an easy to understand interface. Using a vibro-acoustic signal analysis, OpenZen interprets the recorded events.
Thus, it is possible to perform TARGETED and EFFECTIVE maintenance on OLTCs and to produce a quick diagnosis for intervention.
