Maintenance and Asset Management are becoming increasingly important. The aim is to reduce the costs for replacement and repair and to increase the lifetime of your capital goods. Also unexpected breakdowns should be avoided under all circumstances. Beside the early determination of possible malfunctions a very important aspect is the reduction of maintenance and repair costs.
High reliability is equal to an increase in efficiency and profitability.
Insulation Oil is considered to be one of the weakest points on a transformer. This perception must be considered in any maintenance concept. The lifetime of transformer oil is not equal to the lifetime of a transformer itself. There are several predictive maintenance techniques to take that into account and determine the condition of the insulation oil.
The most known measurements are:
- Dielectric strength testing
- Loss factor measurement in oil
- Water content measurement accord. to Karl Fischer
- Total gas content measurement
- Dissolved gas analysis
All these parameters will give you a clear understanding of the overall condition of your transformer oil.
Oil Sampler Kit for Oil Sampling
Contamination-free Oil Sampling according to standards – with the Oil Sampler Kit
- no contamination with the ambient air
- ease of use
- auto registration the oil temperature
- Measurement according to standard IEC 567 and ASTM 3612
Total gas content
Automatic analysis of the dissolved gases in oil-filled transformers
The analysis is done in 2 steps which guarantee a very high selectivity and sensitivity of the determination of dissolved gases:
- Gas separation by means of fully vacuum degassing ( accord. to DIN EN 60567, DIN IEC 599 and IEEE C57.104-1991) and display of results
- Option: Subsequently to the determination of the total gas content a gas chromatographic analysis can be made

Tan Delta Test Set – TDM 4000
Automatic Dielectric Constant Tan Delta & Resistivity
Test Set –TDM 4000
The TDM-4000 is an automated instrument for measuring the electrical characteristics of transformer oil, insulating liquids & other insulating material samples. The TDM-4000 measures Capacitance, Dielectric Constant (Î), Dielectric Loss, Tan Delta (Dissipation Factor), Resistance & Resistivity of the test sample. The Tan Delta value gives an indication of the condition of the oil sample. There are several reasons due to which the Tan Delta value may be affected – such as moisture, dissolving of some of the transformer varnish, insulating material deteoriating etc.
