摘要	PURPOSE:To facilitate the distinction of electric discharge when a partial electric dischrge test is to be performed by a method wherein disconnection and reconnection between the single-phase transformers of the plural number connected in parallel according to switchgears provided in a duct are enabled. CONSTITUTION:The terminals of the shunt windings W1, the series windings W2 and the tertiary windings (w) of the single-phase transformers 1A, 1B are connected in parallel mutually by lead wires 3, and the switchgears 11 are inserted in the lead wires 3 thereof. When the partial electric discharge test is to be performed at the construction like this, the whole switchgears 11 are closed at first to apply a test voltage, and when partial electric discharge is generated, the switchgears 11 are opened wholly, the test is performed only by the single-phase transformer 1A on one side to distinct in which single-phase transformer partial electric discharge is generated. Moreover when load becomes to light load of 20% or less when operation is performed in the condition that the switchgears 11 are wholly closed, the whole switchgears 11 are opened, and favorably effective operation is performed by one single-phase transformer.
