Abstract
A current transformer connector () for connecting a current transformer of an electrical network to a protection relay via a current transformer data acquisition board (), is provided. The current transformer connector () comprises first and second pairs () of first and second current contacts (), each current contact pair () being connectable in use to the current transformer so as to permit current flow from the electrical network through the current contact pairs () to the protection relay. Each current contact pair () is arranged to be in a short circuit configuration. The first current contact () in each current contact pair () is arranged to be independently moveable relative to the corresponding second current contact () so that during initial insertion of the current transformer data acquisition board () into the current transformer connector () in use the first current contact () of the first current contact pair () is configured to separate from the second current contact () of the first current contact pair () to permit breaking of the short circuit configuration of the first current contact pair () and making of an electrical connection between the first current contact pair () and the current transformer data acquisition board (), while the second current contact pair () remains in the short circuit configuration. The first current contact () in each current contact pair () is further arranged to be independently moveable relative to the corresponding second current contact () so that during further insertion of the current transformer data acquisition board () into the current transformer connector () in use the first current contact () of the second current contact pair () is configured to separate from the second current contact () of the second current contact pair () to permit breaking of the short circuit configuration of the second current contact pair ().
