Transformer Monitoring and Diagnostics

Our solutions and products enable our customers to capture and analyse critical data in order to monitor transformers, detect impending failures and thus avoid or reduce unplanned outages. Our solutions are available across multiple industries like Power Utilities, Petrochemical Plants, Metals and Transportation Industries.

We offer a broad range of asset monitoring and diagnostic solutions delivering increased operational availability and performance.

As the leading provider of technology that predicts transformer failures, we are distributors of GE Digital Energy products in South Africa.

The GE type monitoring and diagnostics equipment empowers customers with real time information that leads to more informed decisions taken. With proactive and increased asset information, our customers can improve reliability of their plants/networks, reduce maintenance expenses, proactively manage performance and delay or reduce capital expenditure.

We provide the customer with a solution whereby the condition of the installed fleet of transformers can be monitored to determine whether the transformers are fit for purpose, need maintenance, refurbishment or replacement.   The oil samples can be taken as per the customer requirement, be it daily, weekly, etc. This information can then be configured by the Perception software and communicated to the control room via the telecontrol equipment.

The process of analysing the dissolved gases and the concentration thereof present in a transformer’s oil is the key to the solution. Our solution includes the installation of units that range from single gas monitoring units to multi gas monitoring units depending on the function and application of the transformer. The solution we offer employs the Photo –Acoustic Spectroscopy technology to analyse the gases in the transformer oil. 

The product range to be used in our solutions varies from single gas units (plus moisture) to multi gas units. In addition to the gases being monitored, these units also monitor the oil moisture content.

The gases we detect are:

  • Hydrogen - General fault gas
  • Carbon Monoxide - Overheated paper insulation
  • Methane - Overheating of oil 200ºC to 500ºC
  • Ethane - Overheating of oil 300ºC to 500ºC
  • Ethylene - Overheating of oil above 500ºC formation of carbon particles
  • Acetylene - Electrical arcing
  • Carbon Dioxide - Severe oil oxidation
  • Oxygen - Oxidation
