Asset health management on MV switchgear

Want to mitigate the risks posed by your MV switchgear failing and leaving your plant without power when you need it most?

Pragma provides an engineering support service that provides:

  • Improved MV switchgear availability
  • Extended asset life
  • Reduced business interruption risk
  • Increased cost transparency and predictability
  • Lower health, safety and environmental risk

Large industrial, mining, petrochemical, utilities and municipal owners are dependent on the reliability and availability of their MV switchgear to distribute and supply their plants or customers with electricity without interruption and to protect the network in case of faults. If MV switchgear fails, it can be catastrophic and lead to a loss of life, business and service delivery interruption, reduced income, brand equity and much more.

By continuously monitoring these assets you have factual and real-time information about the health of these assets and are able to make quick decisions and take action.

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.

Asset Health Managment - Implementation and Operational Model

Our scope

Assets we cover

  • MV switchgear

Industries we serve

  • Manufacturing
  • Mining
  • Petrochemical
  • Public Sector, Metros, Municipalities, Water boards
  • Energy generation, transmission and distribution (incl. Renewable Energy)

Your challenges

Asset Reliability Risk

  • Catastrophic failures including fires, gas emissions and explosions
  • Consequential damage to equipment controlled by switchgear is potentially significant
  • Business interruption is a major consequence of switchgear failure

Impact of poor maintenance practices

  • Statutory compliance work not recorded
  • Remedial work not managed
  • Maintenance work quality not ensured
  • Reduced asset reliability

Statutory and Safety Risk

  • Significant risk human life in case of catastrophic failure or failure to function as electrical circuit protection and isolation
  • Management of statutory requirements, incl. having panels and protection schemes verified, maintained and tested annually or in accordance to network regulations
  • Poor compliance to regulatory or risk requirements (also for insurance)

Our value

Improved business sustainability

  • Efficient implementation of digitalised maintenance processes
  • Reduced business interruption risk through reliance on switchgear expert monitoring and advice
  • Critical information provided to enable agile decision making

Switchgear availability assurance

  • Continuous trending of asset condition parameters, incl. partial discharge, temperature, humidity, load and power quality
  • Advanced diagnostics on-site to support fault finding efforts and take corrective action before failure
  • Reactive and predictive maintenance work identified, planned and executed by expert field technicians
  • Maintenance work inspected to ensure quality
  • RCM based maintenance plans

Best-in-class monitoring solution

  • Supply and installation of industry-leading monitoring technology
  • Intelligent Gateway that bridges the gap between edge devices and the cloud irrespective of interfaces and protocols
  • Use of cutting edge analytics to process asset condition data
  • Web-based IoT monitoring platform for easy and remote access to condition parameters

Improved cost transparency

  • Maintenance spend planned, benchmarked and controlled
  • Asset life-cycle cost managed based on reliable information
  • Reduced fixed-interval maintenance – only act when required

Client Reference | Online Condition Monitoring for Gas Power Plant Generators

The client is an integrated chemical and energy company that produces a range of high-value product streams, including liquids, fuels, chemicals and low-carbon electricity. A few years ago the client began producing power from a newly built gas engine power plant which has an export capacity of 140MW and is one of the largest power plants in South Africa using gas.

Client Reference | Real-time Condition-based Monitoring using IIoT Technology

The client is a manufacturer of glass bottles for wine and carbonated soft drinks. Manufacturing of glass products is an energy-intensive process, and the supply of electricity to the plant is critical to the operation.

Introduction Resin Cast Transformers

Researching the advantages of cast resin transformers, you may find the information available to be somewhat lacking. Many resin cast transformer companies mention that these transformers only need air to cool, due to its smooth coil surface eliminates heavy dirt build-up.
