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
Capacitance and power factor/dissipation factor measurement
DC winding resistance measurement and OLTC verification
Transformer turns ratio (TTR) measurement
Exciting current measurement
Short-circuit impedance / leakage reactance measurement
Demagnetization
Online and offline partial discharge testing
