Asset health management on transformers
Want to mitigate the risks posed by your transformer failing and leaving your plant without power when you need it most?
Martec provides an engineering support service that provides:
- Improved transformer availability
- Extended asset life
- Reduced business interruption risk
- Increased cost transparency and predictability
- Lower business risk
All electricity users and plant owners are dependent on their transformers to keep their plants or networks in operation. Transformer failures can be catastrophic and dangerous and lead to a loss of revenue, products, service delivery, income, brand equity and much more.
By continuously monitoring these assets you have factual and in-time information about their condition and are able to make quick decisions and take actions, to ensure their availability.
For us, it is more than just monitoring
We follow an end-to-end implementation and operation’s approach to asset health management that includes a structured framework with asset type-specific features.
Our scope
Assets we cover
- Transformer
Industries we serve
- Utilities
- Generation and Transmission
- Mining
- Manufacturing
- Renewables
Your challenges
Transformer reliability
- Degradation or contamination of oil insulation
- Overheating and thermal degradation
- Low insulation and cooling oil levels
- On load tap changer failure
Transformer risk
- Business interruption and long repair/replacement lead time in case of failure
- Potential for catastrophic and harmful failures
- Lack of redundancy or mitigation plans
Impact vs Probability
- Complacency due to low frequency and high reliability of transformers
- Limited consideration for the high impact in case of failure
Impact of poor maintenance practices
- Statutory compliance work not tracked
- Remedial work not managed
- Maintenance work quality not confirmed
- Reduced asset reliability
