 Sumpner'​s test is used for large transformers,​ for which ordinary full-load tests are too expensive from the viewpoint of electrical energy consumption and difficulties in finding a suitable load capable of absorbing nominal power of the transformer. This is especially difficult, because the thermal tests require operation under full load for many hours, in order to achieve thermal equilibrium.[(Ghosh)][(Rajput>​[[http://​google.com/​books?​isbn=9788170086093|R.K.
