PRODUCT DETAILS

What is CT sensors

Current transformers (CTs) are sensors that are used for measuring alternating current. They are particularly useful for measuring whole building electricity consumption (or generation for that matter).

The split core type such as the CT in the picture above, is particularly suitable for DIY use it can be clipped straight on to either the live or neutral wire coming into the building without having to do any high voltage electrical work.

    The non invasive ac current sensors are really great. I have a great use for several (8) of them.
    My problem concerns measuring power supplied by my Solar Inverter being consumed by myself or sent back to the power grid. Technical issue is that it's not possible to directly measure direction of current flow in and out ofcthe power grid. It's just as current.
    What I want to do is to place one sensor behind each circuit breaker on my power board plus the grid breaker and the inverters breaker.
    By measuring all the currents I should be able to compute in real time how much power is going from inverter into grid and/or how much used in my house.

    The non invasive ct sensor seems safest way to measure the current flow. Problem is how to connect and read 8 of them at the same time.
    It would be helpful if Seeed could produce a grove sheild that does the following:
    1. Provide 8 sockets for CT plugs as inputs
    2. Provide protection zenerdiodes for each input and voltage divider resistors. Provide resistors in little sockets so the voltage divider can be altered if necessary, but by default allow connection of a range of different CT types e.g. 10 A, 20 A, 50A, 70A etc.
    3. Scan each input continuously and measure current by fast A to D conversion (or multi channel A-D) and store the result in onboard Register (short term memory).
    4. Provide I2C interface allowing latest measurements to be read by MCU and for parameter adjustments.
    5. Parameter adjustments include setting of full scale current expected on each input. Mains voltage 110 volt or 250 volt or something else.

    Does it seem too ambitious ? Is it expensive to build ?
    Is there a market to sell it ?
    A small version with just 4 inputs would be OK too.
