Greetings all,
In the past I've needed to produce three phase 50 Hz power to do safety, EMC
testing as well as certain validation tests. I've used several methods
including gas powered
Many years ago, a local test lab in Newburyport, MA used decommissioned
hydroelectric
generators driven by electric motors for their AC mains testing.
For 50 Hz they dropped huge resistors (carbon piles???) in the river and
just loaded
down the motor-generators. The boiling river water,
I've worked with both brands in the past, as well as Elgar in the 100 kW
range. I found the CI to be a little more fragile than the PP units as I
believe the current sharing scheme of the parallel AC modules was not the
best design. I am thinking about this option, if I can find a suitable
California Instruments or Pacific Power agile power supplies. 480VAC 60hz
input, variable output. If >250V l-l is needed, add a step-up transformer
to the output. Pacific Power 3060MS cabinets can be paralleled to
significant output levels. I assembled a lab with about half a megawatt of
Greetings all,
In the past I've needed to produce three phase 50 Hz power to do safety,
EMC testing as well as certain validation tests. I've used several methods
including gas powered generators, electric motor-generators with different
sized pulleys and of course AC Power Sources. Once again,
