Transformers Condition Assessment Services
SNAGS Transformer Testing service offers a comprehensive range of diagnostic tests to assess the condition of transformer. Results can be used to identify transformers at risk of failure, to improve performance and extend transformer life.Power transformers are among the most strategically important and expensive components on any network. SNAGS 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.

Overview of Routine Transformer Testing Services
SNAGS performs industry standard inspection testing includingElectrical tests
- Oil tests
- Transformer Visual Examination
- Tap-changer Test
Advanced Diagnostic Testing
When routine tests such as DGA or Power Factor indicate potential issues, SNAGS can perform advanced diagnostic test techniques to determine the root cause of the abnormalities. Our diagnostic techniques include:
- Partial Discharge (PD) testing
- Dielectric Frequency Response (DFR)
- Frequency Response Analysis (FRA)
- Dynamic Resistance measurement test on OLTC
- Moisture measurement test on insulation/paper
- Moisture measurement test on insulation/paper
For early detection of insulation breakdown in cable boxes As well as being an essential part of condition based asset management, Transformer Testing should also be undertaken when a new transformer is commissioned as a fingerprint data collection for later comparison, following repairs and to diagnose faults. Regular Transformer Testing, to identify faults early, will minimize expensive replacement costs.
This is a unique service that SNAGS offers after a transformer is taken out of service. SNAGS proposes a root-cause failure / post mortem analysis be performed to help prevent similar failures, better understand aging mechanisms, or predict the life of similar transformers currently in service.
BENIFITS & FEATURES
- Locates PD activity before it leads to failure
- Ideal for pre-commissioning or post-repair
- Reduces the need for expensive excavations by identifying the location of the problem
- Reduces the risk of unplanned, expensive outages
