Re: 3 - phase HV supply
Dick, That's a heck of a lot cheaper than here in the states. Esentially, the monthly charge here is renting the transformers, even though you pay the large fee to have them hung on the pole and

Few questions
All, I have a HP 412A VTVM coming in, and I'm wondering what others may know about these? Anything I should look for, etc.? These don't have the rectifier tube in the probe like the 410 models do, but

Re: 3 - phase HV supply
Euro 175.- to get concerted from single phase service to 3 phase service in the Lowlands. For that money you'll get: 3 fuses a new 3 phase digital power/kWh meter 3 x 35 amps @ 400 VAC ( 42 kW AC, gud

Rotary Switches
Can anyone tell me how to select unmarked wafer switches for RF switching, such as e-shopping at Surplus Sales? What is the general rule regarding contact spacing vs HV? If unmarked, how do I get into

Re: 3 - phase HV supply
Denny, A rotary converter (pony motor) is the only way to do it correctly. A static converter is simply a started capacitor bank to get the motor up to speed then it drops out letting the motor run on

Re: 3 - phase HV supply
Being that my Bridgeport mill is 1.5 HP, I use a rotary convertor to change the 220X1 to 220X3... Not perfect but it works... I did consider asking Consumers Power Co. to give me a price for 3 phase

Re: 3 - phase HV supply
A 3 phase service is mighty fine to have if one can afford to have it put in. I've not checked on the price in a while, but back in 1985, a 200 amp 220 volt service ran around $2000 from the power
