Method of A.C. insulation testing utilizing a variable inductive reactor in parallel with a test specimen |
摘要 |
Insulation is tested by the method of connecting a variable inductive reactor across a voltage supply in parallel with a test specimen. The inductance of the reactor is varied until its reactance equals that of the sample as indicated by the supply current to the parallel circuit.
