Description

Measure the eletric power with this non-invasive 100A clip ampmeter

Here is a CT familly sensor (Current Transformer) used to measure alternative current up to 100 Amp (we do also have a 30A version). They are great to mesure power consumption into house, building without modifying them! They are also welcome to monitor the current/power production from an autonomous power generator.

The sensor ring is splitted in two part (see product pictures), which make them easy to clip it around the the grid phase to monitor. Open the clip, place it around the power wire to monitor, close the clip.

Thank to this clip system, you can clip it on any power grid by minimising the electrical shock and without the need to shutdown it for modification.

Applications

  • Great to measure current
  • Monitor and protect alternative motor
  • Lightning equipement
  • Air compressor

Specifications

  • Model: YHDC SCT-013-0100 (also named SCT-013-000).
  • Input current: from 0 10 100A AC
  • Output: from 0 to 50mA AC

  • Learning about the SCT13-000 (100A) sensor on openenergymonitor.org.
    Lot of informations and very interesting.
Notes:
  1. This sensor does not includes the burden resistor. It is needed to convert the sensor current into an analog output voltage. See our French tutorial for more informations.
  2. The output should be protected with a TVS (Transiant-Voltage Supressor, ou Diode Transil wikipedia.fr).
    I didn't find any specs about such protection diode, the informations collected on openenergymonitor.org let me think that cutout voltage is quite higher than Analog entry can support.

Using the sensor

This sensor do not have any "Burden" resistor, you must wire a resistor in parallel with the sensor output to transform the current into voltage (u = Rburden x Isecondaire). See our french tutorial for more details.

As this sensor act as a transformator, the sensor output is also and alternative current (and alternative voltage on the burden resistor). This means that the output signal oscillate around the zero volts (once negative, once positive, and so on).

Most of microcontrolers, like Arduino, Pyboard, Pico, etc) do have analog input. However, they don't accept negative voltage. DO NOT WIRE THIS SENSOR DIRECTLY ON MICROCONTROLER.

You must use a voltage divider to shift up the full output signal to the positive area (over 0 Volts). This is a simple voltage . See our tutorial (in french) for more details about the wiring.
