Ct shorting terminal block wiring diagram. Captive hardware finger safe covers din rail mounted safer than traditional shorting blocks easier to install eig offers two options for ct shorting for meter installation. Test and measurement with rt 5 t sliding link terminal blocks phoenix contact duration. Shorting the secondary with primary current present allows other connections to be removed if needed. A wiring diagram is a streamlined standard pictorial depiction of an electric circuit.

An open ct secondary with primary current applied produces a hazardous voltage which. Ct cable was a spare cable and shorted at the terminal. 4 pole block part. 4 pole and 6 pole ct shorting blocks features include.

I think you can get an idea from the photos of what they do. Four or six pole shorting blocks can be used in applications with up to three current transformers as shown in the diagram below which allows each current transformer lead to have an individual contact point. Wiring diagram ac schematic information. There are shorting links for the ct connections and disconnecting links for the voltage connections.

Ct shorting blocks are used to create an intermediate contact point between the meter and load where it is safe to perform wiring alterations. Unused ct inputs could possibly pickup electrical noise so it is a good practice to short out unused ct input terminals by connecting a wire jumper about 1 inch long between the white and black ct terminals. Schematics and this kind of picture transformer block diagram luxury current transformer connection diagram ct. It shows the parts of the circuit as simplified shapes and the power as well as signal connections between the gadgets.

It will be easier to connect the wires to the terminal block if the block is first plugged into the meter. This test block is the sort of thing we usually use. The screws connecting the conductors are only accessible after the current transformer has been short circuited using the short circuit slider. Terminal blocks may have shorting capability but ct circuits can pass through have some wiring diagram information shown on them.

Wiring between the cts and the power monitor should include a shorting terminal block in the ct secondary circuit. Ct shorting blocks are wired such that the negative leads of the current transformers are connected to the same node and tied to ground. Demonstration of shorting a ct shorting block for safe wiring modifications. With our test disconnect terminal blocks based on tested weidmüller screw connection technology connecting challenges can be resolved clearly and cost effectively.
