Product Description
The series of open-type current transformers are specially designed to facilitate the installation of circuit systems or power distribution system renovation projects. They can be installed without disconnecting cables or bus bars, which saves installation time and maintenance and renovation costs.
1. The operation requires professional electricians to wear protective gloves, or the secondary line is disconnected and then installed!
2. The primary of the current transformer should be connected in series with the current loop under test, and the secondary should be approximately working in a short-circuit state!
3. The secondary of the current transformer No open circuit is allowed, so please do not install a fuse.
4 If the open current transformer is installed with power, the secondary circuit needs to be connected, and then the screws are tightened when connecting to the primary
