    transformer radiation

    It will be in a metal skin with lost of "square mesh" as the front and back of the unit. Is there a way of determining the radiation levels?

    transformer radiation

    I'm building a moly glass furnace that requires a 40kva transformer. The transformer might need to be inside my building. How do I determine emf...radiation levels from the transformer and the safety protocols...distance from, shielding, etc. Thanks,Virgil

    building voltage drop

    a little more on what I currently (the 100lber)have: controller has 4-20 milliamp output capability current limiting scr transformer plate reads: marcus transformers model 15G45-20T 240 primary 45 secondary kva 15 hz 60 single phase type wm temp 150 C class 220 spec. 9155 connect: cu/al...

    building voltage drop

    thanks for the replies 7anoter4 the underground line from the splitter box is about 400ft...and 700feet before that and it looks like a bigger box at that location...MAYBE a transformer???...I don't know about the utility company transformers. They said I had more than enough for 400amps...did...

    building voltage drop

    As on a previous thread I'm building a new 400lb studio glass furnace to replace the current 100lb glass furnace. Now going Moly elements 9 elements 9/18 312/500 60amp 12.5 volts each wired in 3 series of 3each 40 kva transformer 4 to 1 step down furnace will run on separate 200amp...

    Contoller questions for glass furnace

    not a reduction atmosphere and with the moly AND a transformer I can more power to the elements.

    Contoller questions for glass furnace

    So, after a couple of weeks of educating myself on the SIC element system and molybdenum disilicide (MoSi2) element system I will be going with the Moly elements. Initial costs are much more, but should be cheaper in the long run...longer element life to go with 10 year or more of life of the...

    Contoller questions for glass furnace

    Propane in this application (studio glass furnace) is at least twice as expensive. Three-phase in not available. With further discussions today with Larry at Watlow it looks like I'll be using the SCR with current limiting and be able to lower the amps. This will reduce costs and take care of...

    Contoller questions for glass furnace

    I’m in the process of building a studio glass furnace and have concerns about the set-up for the control system. I have 240V single phase 400amps into the building off a 350 aluminum underground line. Furnace will be on a on a separate 200 amp circuit. Breaker in the box and then fused...
