a second circuit point in the first circuit; —tapping off a test voltage between two circuit points in the first or second circuit, wherein one of the two circuit points is different than the first circuit point and the second circuit point; and —testing the transformer on the basis of ...
A factory overload test of up to 150% of the nameplate rating was run on a 224 MVA autotransformer. The results of this test were of great value and were used in identifying transformer overload limitations, in evaluating loading guide oil and winding equations, exponents and time constants,...
This paper summarizes the results of a functional life testing program conducted over a period of several years on low voltage resin encapsulated electronic transformers. The program was designed to establish how much environmental factors, such as thermal cycling, humidity, vibration, cold shock, over...
section have been developed for testing transformer protection. Currently only single phase models are available. However, single phase models can be inter−connected to form three phase transformers. Processing of three single phase models can be done on a single DSP using the s 正在翻译,请等待...
The main function of the door is insulation. It is a safe protection unit for operator. If you open the door when the tester is in work condition the tester will cut off power supply of high voltage transformer. 3 part 3 shows the micro printer...
Among dielectric strength tests for an oil-filled transformer winding, an induction dielectric strength test requires a large core cross section. Usually frequency of a source for test is 3-4 times of commercial frequency. Therefore, in the case of the induction dielectric test whose magnification ...
