Product Description

Product Description

The Transformer Short-Circuit Impedance Tester is a new generationof transformer parametertesting equipment developed independently by our company.It is used for low-voltage short-circuitimpedance measurement of main transformers of 35kV and above under field and laboratoryconditions.
Short-circuit impedance is an important parameter of transformers.The short-circuit impedancemethod is a traditional way to assess winding deformation.According to GB1094.5-2003 andIEC60076-5:2000,the change in short-circuit reactance is the sole criterion for determining whetherthe transformer winding is deformed.
