    Basic question, but I have a doubt! I have a pool heater that works from 240 volts. In order to calculate the annual operating cost, I installed a device that measures amperage and adds up the total consumption in Kwh (see image for reference). The device measures by induction amperage...

    My machinery has a range of 120 – 240 volts. I have to run quite a few of these. My input voltage from the utility company is 12000 Volts and I need to step it down to 208 Volts. What kind of transformer do you suggest? I want to run the machines on 208 volts so that my amperage is less. 1)...

    Hello.. I am curious how or why there is a higher amp draw on an induction motor during an under voltage condition. According to ohms law, isn't amperage directly proportional to voltage? I am just confused and can not seem to find the correct answer to help me understand how or why this works...
