Hopkinson's test

WebAug 20, 2024 · Hopkinson’s test is a method of testing the efficiency of DC machines. The Hopkinson’s test is known as regenerative test or back-to-back test or heat-run test. This test requires two identical shunt machines which are mechanically coupled and also connected electrically in parallel. One machine acts as a motor and the other as a … WebImpulse Test concepts by Philip J Hopkinson, PE Good impulse Test : 1. Higher line terminal voltage than can occur in the field 2. Able to excite all natural frequencies of the windings Ideal Impulse Test 1. Fast rising wave. 2. Significant hold time 2. Severe chop wave. 3. Includes test with shorted terminals of untested windings 4.
