●●● Transformer Factory Acceptance Test:
• Measurement of winding resistance
• Measurement of voltage ratio and check of phase displacement
• Vector Group Test.
• Measurement of short-circuit impedance and load loss .
• Measurement of no-load loss and current .
• Dielectric routine tests .
• Tests on on-load tap-changers .
• Determination of capacitances. windings-to-earth and between windings
• Measurement of dissipation factor (tan δ)
• Temperature-rise type test .
