Power transformer diagnosis 12-420 kV

Neka now offers complete diagnosis of power transformers and bushings.The testing can either be part of the commissoning of new transformers or as a condition assessment of aged transformers.Various influences can affect the life expectancy throughout a transformer's life cycle. Testing and monitoring will help you determine the condition of the asset and select the appropriate corrective measures to ensure reliable operation and extend the life of the transformer- We carry out the most common tests

1. Capacitance and power factor/dissipation factor measurement

2. DC winding resistance measurement and OLTC verification

3. Transformer turns ratio (TTR) measurement

4. Exciting current measurement

5. Short-circuit impedance / leakage reactance measurement

6. Demagnetization

7. Online and offline partial discharge testing
