Negative Values

    • Autor

    Hi! I need your help again please. I have used a Shelly EM to mesure my oven and my induction hob. On oven the measure appears 0 watts, but on the induction hob appears -11 watts (a negative values) with the hob off. When i connect the hob appears positive values as expected but at off position appears negative values.... I have already changed the clamps 1 to 2 and 2 to 1 and always appears a negative value. It's possible to put to zero?

    Regards

    Very likely, the induction hob does contain some parts to correct the power factor and to diminish rf interference, which are not switched off by the power on switch. Thus, you’ll get a capacitive reactive power consumption in idle state. This is quite normal and correctable.

    And you are shure to have the same L on both ?

    Yes i have! The Live it's the same to both. Hob and Oven but i have two claps (one to Oven other to Hob) connected to Shelly EM! The bad of situation it's the consumption appears incorrect because the negative values!
