Large power transformers are in the power range above 250 mva, generator and network intertie transformers with off-load or on-load tap changers, or a combination of both, are recommended. Depending on the on-site requirements, they can be designed as multiwinding transformers or autotransformers, in 3-phase or 1-phase versions. Even with ratings of more than 1, 000 mva and voltages up to 1, 200 kv (800 kv), the feasibility limits have not yet been reached. We manufacture these units according to iec 60076 as well as other international and national standards (e.G., ansi/ieee). Generator step-up (gsu) transformers Gsu units transform the voltage up from the generator voltage level to the transmission voltage level, which may be as high as 1, 200 kv system voltage. Such transformers are usually ynd-connected. In order to make an inquiry regarding a gsu power transformer, the technical data for the items in this section are required. Step-down transformers Step-down transformers transform the voltage down from the transmission voltage level to an appropriate distribution voltage level. The power rating of step-down transformers may range up to the power rating of the transmission line.

Product Introduction With the continuous update and expansion of modern technology higher requirements are put forward for the reliability of power system and high-voltage equipment. Accidents or damage of electrical equipment are usually closely related to insulation defects. Large capacity of electrical equipment high voltage structure diversification and sealing electrical equipment should be put forward a new higher requirements. With the increasing use of large-capacity equipment the insulation performance cannot be detected by ordinary megohm meter. Power test procedures for a number of power equipment such as: cable motor generator transformer transformer high voltage switch lightning arrester and other requirements to do a series of insulation performance tests the first is to do insulation resistance test. When testing the insulation resistance of large-capacity power equipment the insulation resistance value is related to the pressurizing time. The longer the pressurizing time is the higher the insulation resistance value is. This phenomenon is called insulation absorption phenomenon. In order to understand the insulation performance of the subject it is necessary to conduct the absorption ratio and polarization index test first so as to provide safety guarantee for the next leakage dielectric loss partial discharge and insulation performance test.
