DP(III)-30*20
Description:
It is mainly used for measurement and protection of electrical equipment in 0.66KV AC power system. It can also be used in conjunction with relay protection ,measurement and metering devices and is widely used in urban and rural power grid reconstruction .This type of transformer is easy to install ,does not need to remove the wire once and can also be operated with electricity which does not affect the normal installation and use of customers.
Separate structure ,easy to install and easy to operate .
The iron core can be divided ,the precision is high and the magnetic circuit is small.
For current measurement ,monitoring and protection of lines and equipment.
Internal windows are large and can pass through clamps, cables or busbars.
