Transformer Testing

From commissioning to asset management, LIVE HV provides a complete range of testing services for your high voltage transformers.

While the most common and very successful method for analysing transformer condition is oil sampling, there are many cases where high voltage testing services are required and beneficial. In addition to online PD testing and bushing tap sensor installation, LIVE HV provides a complete range of transformer high voltage testing services for commissioning and shutdown maintenance.

  • Bushing Tap PD sensor installation
  • Oil Sampling
  • Partial Discharge testing
  • Dielectric Dissipation Factor (DDF)
  • Turns Ratio test
  • Insulation Resistance (IR) & Polarisation Index (PI)
  • Sweep Frequency Response Analysis
  • CT Burden & Excitation
Online PD Testing Transformer

Online PD testing produces an instant condition assessment of your transformers insulation via spot testing; or extended monitoring is performed to determine how operational and environmental impacts affect the transformer during regular use. Measurements are taken while in service via bushing tap sensors, acoustic sensors or HFCT’s attached to connected HV cables.

Key Benefits

  • Identify & monitor insulation damage prior to failure
  • Trend insulation condition without outages
  • Acoustic testing for defect location
  • Reduce downtime & increase safety
