Transformer Testing

EA Technology’s Transformer Testing offers a comprehensive range of diagnostic tests to assess the condition of key transformer assets. Results can be used to identify transformers at risk of failure, to improve performance and extend transformer life, and also form a vital part of any condition based asset management programme.

• A full suite of five state of the art tests
• Helps avoid expensive failures and downtime
• Helps improve transformer loading capability
• Helps develop Health Indicies and predict End of Life
• Provides essential data for cost effective asset management

Power transformers are among the most strategically important and expensive components on any network. EA Technology’s diagnostic Transformer Testing uses the very latest techniques and equipment to accurately assess the condition of these key assets, ensuring optimum performance and identifying potential faults before they lead to failures.

The Transformer Testing includes:

• Static and Dynamic Resistance and Impedance Measurement – to assess tap changer condition
  
  
• Tan Delta Testing – to assess bushing condition
  
  
• Frequency Response Analysis – for early detection of transformer faults
  
  
• PDC-FDS Measurement – to establish moisture levels in solid insulation
  
  
• Partial Discharge Measurement – for early detection of insulation breakdown

As well as being an essential part of condition based asset management, Transformer Testing should also be undertaken when a new transformer is commissioned, following repairs and to diagnose faults. Regular Transformer Testing, to identify faults early, will minimise expensive replacement costs.
