Abstract

The current transformer assembly has three current transformers (1,2,3) for detecting current flowing through the fuse block. Each of the current transformer has primary conductors (10,12) circumferentially surrounding the core. The coil shaped core surrounds the core secondary conductor. The ends of the secondary conductor have a measuring port, and the primary conductor is connected to output connection of the fuse panel with a connecting cable. An independent claim is also included for a fuse panel.
