Product Specifications
Product Description
Current transformer is a power transformer transforming high voltage and current into low voltage and current. Its primary winding and primary circuit of electric system are tandem connection. Its secondary winding and measuring meter, relay of secondary are also tandem connection. Its main structure is made up of primary, secondary winding and magnetism iron core.
Current transformer conforms with IEC60044-1, 1996 standard. There are two sorts for measuring and protection.
Measuring current transformers are construct to measure current and electric power. These type of current transformers are mainly used as class 0.2, 0.5, 1.
Protection current transformers are used for relay protection and automatic controlling device. These type of current transformer are mainly used as class 3.
Founded in 1986, our company produces more than 70 types of current and voltage transformer with over 1000 specifications, in which Grade 0.2 high voltage electric power measuring tank has passed the type test conducted by Wuhan High Voltaage Measuring Institute in May, 1999. Products with current grade of 0.38kV-35kV and accuracy grade of 0.2, 0.5, 1, 3 are avaiable, whichare designed in accordance with GB1208-1997, GB1207-1997 national standard and IEC standard respectively. It was certified to ISO9001 and awarded the qulified certificate of adopting international standard.
It is widely used in various electric power station, electric power plant, factory and electric power system, and sold well in each province, city and autonomous region in our country and used together with national major projects for many times. Some of our products are exported to countries in Southeast Asia. In addition, we also offer the transformer with specifications and uses according to clients' requiements.
