Deep online analysis of dielectric parameters for lubricants with an innovative oil sensor system:
Identification of critical operation conditions of industrial gearboxes for reduction of failure
rates and live time enhancement
T
he requirements in the energy sector for large industrial gearboxes as installed in wind turbines or in gas/diesel
engines rise. Ever more flexibility at a maximum operational reliability and a long life time are required of them at
the same time, so the requirements for the oil and the oil condition monitoring grow correspondingly. This presentation
provides information about a novel online oil condition monitoring system to give a solution to the mentioned priorities
for the energy sector. The focus is set to industrial gearboxes but the possibilities in monitoring of related applications are
also addressed. The online oil sensor system is based on the measurement of the components of the complex impedance of
oil, in particular, the components conductivity kappa, the relative permittivity epsilon r and the temperature T, which are
acquired independently from each other. Based on a very sensitive measurement method with high accuracy even small
changes in the conductivity and dielectric constant of the oil composition can be detected reliably. The new sensor system
effectively controls the proper operation conditions of industrial gearboxes and in test rigs for electrical vehicles, where
lubrication and isolation of the oil has a double function. 24/7 online monitoring of the asset during operation enables
specific preventive and condition based maintenance independent of rigid inspection intervals. Corrective procedures
and / or maintenance can be carried out before actual damage occurs.
