Transformer Is the Heart of Any Power System. Hence Preventive Maintenance Is Always Cost Effective and Time Saving. Any Failure to The Transformer Can Extremely Affect the Whole Functioning Of The Organization.
Transformer Oil Testing
- Transformer Oil Testing and Analysis Is Useful in Monitoring The Condition Of Electrical Equipment.
- Transformer Oil Used as Insulator and Coolant in Oil Filled Electrical Equipment. To Prevent The Equipment From Arcing, Partial Discharge And To Dissipate The Heat, Oil Is Filled In Transformer.
- Transformer Oil Is Also Used to Preserve the Transformer's Core And Windings.
- The Analysis of Insulating Oil Provides Information About the Oil. Regular Testing & Analysis Of Oil Also
- Enables For The Detection Of Other Electrical Problems, Including Contact Arcing, Aging Of Insulating Oil,
- Insulating Paper and Other Faults In Initial Stage.
- Transformer Oil Testing Is An Essential Part Of A Cost-Efficient Electrical Maintenance.
- Transformer LT & HT side rewinding work available.
Moisture Content
The moisture content in the transformer oil needs to be less than 10 ppm at normal temperature. It will affect the efficiency of the power transformer system.
