The Current Transformers (CTs) are essential components of the Vue: Gen 3 home energy monitor, enabling it to measure power consumption in real-time with precision. These sensors are crafted with a unique magnetic material known as Ferrite, which possesses exceptional properties allowing for the accurate measurement of alternating current flowing through any circuit line or wire. Designed for ease of use, they feature a split-core design, enabling them to be easily clamped around a circuit line without the need for detaching the line or conducting any electrical work.

Our 200A CTs are tailored explicitly for placement on the system's main lines, capable of measuring up to 200A when connected to the Vue: Gen 3's main ports (labeled A, B, and C). Meanwhile, the 50A CTs are capable of measuring currents up to 50A. It's important to note that exceeding these amperage limits will not damage the Vue: Gen 3 device or the sensors themselves. They are designed to monitor power passively, ensuring safety and reliability, with measurements capping at the mentioned limits due to the design of the Vue: Gen 3 device ports rather than the sensors themselves.

The number of 200A CTs needed is determined by the phase count of your electrical system, requiring one 200A CT sensor per phase/live main line. It's important to note that neutral and/or ground lines are not considered in the "phase" count.

Absolutely - If you want to use the larger sensors, you'll need to re-attach the sensor wires into the smaller 50A CT-sized terminal block to fit into the side port. It's important that you match the black wire (positive) from the CT to the properly marked black/solid terminal indicator labeled on the device and the white wire (negative) to the white/empty terminal indicator. Once properly attached, you can add a 4.0 multiplier to that circuit within the app settings to adjust the calibration for the different sensor sizes.

Yes, you can. This will require you to re-attach the sensor wires into a 200A CT terminal block for compatibility with the device port and a 0.25 multiplier within the app settings for sensor size calibration adjustments.

We are excited to announce that Flexible Sensors are available for the Vue: Gen 3 devices as of Fall '24. These sensors offer a versatile solution for situations where accessing mains is challenging. Unlike standard CTs, Flexible Sensors utilize "Rogowski coils" and have a separate 120/240V power supply included with your purchase from our shop. These coils are designed to easily attach around a circuit line without disconnection, mirroring standard CTs' convenience.

To ensure compatibility and proper installation space for Flexible Sensors, please look at the specifications yeon our website.
