Designed for ease of installation. Protek Electronics has introduced a novel method of wiring and installing power meters and current transformers. The new 'EasyWire' system substantially reduces the time it takes to wire and install three phase current transformers and multifunction energy meters, thanks to a design that allows plug-in connections to be used for both current and voltage input/output.
These savings are made possible due to the innovative design of both the current transformers and the meters, which allow plug in connectors to be used for both current and voltage input/output. An RJ45 lead is used for connecting between the three phase current transformer and meter, and 'readymade' plug in leads are used for the voltage input.
Daisy-chain up to 32 Meters!... Power up to 32 Energy Meters from a single power source.
Power-up your meter... Plug the ready-made ‘supply’ lead connector into your meter. Connect the other, ferrule tipped, ends to the supply, not forgetting to use the correct fuses, and you’re done.
Connect your current transformer ...... Plug one end of the RJ45 lead into the multifunction power meter and the other end into the three-phase current transformer and you’re done - it’s that simple.
More than one meter?... Plug the ready-made ‘linking’ lead connector from your first meter to your second
This system is safer than using traditional current transformers because Easywire transformers incorporate the resistive shunts usually located within the power meter. This means that the secondaries are always loaded, therefore eliminating the possibility of dangerously high voltages developing during open circuit conditions.
This allows the meter to current transformer to be disconnected without the need for secondary shorting terminals, again saving money and reducing downtime.
