Here’s a question for an Electrician or Electrical Engineer.
After riding out hurricane Irene, we’re dealing with the power outages.
I have a big generator that runs the whole house nicely and then I have a small 900 watt two stroke to run the fridge when the big one isn’t running. I don’t need all that wattage most of the time.
Anyway the two stroke is a cheap china made unit, but it was billed as a “digital inverter†generator. Now it seems to run the fridge OK and anything else that I’ve tried to run.
But here is the mystery. I plugged a Kill-o-watt meter into it to see what it was putting out and what things draw. It showed the generator putting out 118 volts but when I tried to read the frequency it gave me a dC display. Alarmed I plugged it into the big generator and it said 60.1 Hz. When I plug it into the 700 watt camping inverter it says dC, and the pure sine wave inverter says 59.9 Hz.
What is going on? I’m only a poor Mechanical Engineer and this is beyond me.
