Last Friday we exported two sets GDZC-10A Portable Transformer Winding Resistance Tester to our regular customer.It's used to measure dc resistance of transformer or other inductive loads. The max test current is 10A.Compared with ordinary transformer winding resistance tester, this equipment equip

The error of current transformers is divided into ratio error and phase angle error:The ratio error is the current value indirectly measured through the secondary circuit (KeI2 minus the percentage of the actual value of the primary current to the actual value of the primary current). That is, the p

What’s the ZJ Series Vacuum Pump UnitThe Transformer Vacuum Pump Unit is mainly used to extract gas from the container, so that the container can meet high vacuum requirements, and can also be used for vacuum drying. Especially suitable for vacuum pumping in the substation industry, power supply bur
