Repair

Well-equipped facility and resources are available to carry out repairs on all types and kinds of transformers. 

• Repair charges are economical, fraction of cost of a new transformer
• Transformer is re-manufactured strictly as per well-established processes and quality norms  
• Possibility of re-designing transformers to include innovative features  
• Repair adequacy is verified and demonstrated through testing conforming to relevant product standards like IS 2026 / IEC 60076 

Overhauling

Services include 

• Washing core coil assembly with clean oil and re-tightening clamping structures 
• Cleaning core coil assembly and removing sludge to avoid hotspots in core and windings 
• Removing moisture from oil to prevent deterioration of life of cellulosic insulation and monitoring degree of polymerization (DP) of paper 
• Improving insulation parameters like Polarization Index (PI) and Tan Delta 
• Functional checking of supervisory devices like Buchholz Relay, OSR, PRV, MOG, OTI, WTI, etc.  
• Overhauling of OLTC / OCTC, fans, pumps, etc. 

Erection, Testing & Commissioning

Dedicated team of engineers are engaged in services of erecting, testing and commissioning of transformers for long life and trouble-free operations.

Our expertise include: 

• Erection of all ratings of Transformers up to 220kV Class 
• Supervisory Services on third party basis for erection, testing & commissioning up to 220kV Class

Spares

Right Part at the right time reduces down time! We are fully geared to supply spares for all rating and makes of transformers. 

• Spares manufactured as per standard quality norms 
• Sourced from approved vendors 
• Minimum cycle time

Health Assessment

Condition Monitoring and Residual Life Assessment of Transformers prevent catastrophic failures. 

• Residual Life Assessment (RLA) determines residual life of transformer 
• Condition monitoring and recommending condition-based maintenance plan 
• Conduct special tests like Degree of Polymerization (DP) of paper insulation, foreign content in oil, etc. for evaluation and assessment of condition of transformer 
• Health Check-up of OLTC of any kind and make 

Other Services

• Site repair services for all makes of transformers 
• Conduct special diagnostic tests for transformers viz. DGA in oil, thermography, frequency response analysis, on-line partial discharge measurements, etc. 
• Analysis and interpretation of test results for condition assessment of transformers 
• Failure analysis and cost-effective restoration of transformer with minimum down time 
• Annual Maintenance Contracts 
• Any other supervisory & consultancy services
