    Transformer Imbalance Guidance

    Does anyone have any guidance regarding how “imbalanced” the phases can be with a three-phase, 480 to 240 10kVA tranformer? We’ll have a balanced 3-phase source, but our output (load) will have single-phase components and power supplies turning on and off. We won't be able to keep them balanced...

    "For the good of the company"

    Seems to me like they are using the economy's poor condition to take advantage of their workers. You should not have to go insane working 60 hour weeks just to ensure that you have a job in the future. It seems like management is willing to have you work long hours so that they can ensure...

    Looking for some advice

    I'm sort of in the same boat. I graduated in December and had been looking for FT employment, but found a temporary position as a co-op (even though I'm a degreed engineer). Now that the co-op is ending, I'm filling out apps for grad school and going to pursue that route. The market is tough...

    What Is Exptected Of An Electrical Engineer

    What's expected from any engineer is a solid base of knowledge and the willingness to research topics that may arise in the workplace in order to get a job done correctly. Don't say you don't know something, just say you'll look it up.

    $25/hr no overtime pay for PE with 9 yrs exp

    Take it. Sure, the salary is insulting, but at least it's a salary. My college roommate just took a job for $38k without blinking an eye b/c it's better than nothing. He's a recent grad, but it's sort of the same situation as you. Take the job, but keep looking. I hope this helps, and I hope...

    Touch Typists

    I'm also a product of the internet generation. Frantic typing in AIM conversations has boosted my WPM up fairly high. I haven't noticed typing being much of an issue since computers have become a necessity in the workplace.

    Interview questions

    Why me? "Because I'm the right candidate for the position. I'm a hard workerwho enjoys the type of work listed in the position. [Give an example]" Don't be afraid to be a little cocky, but don't over do it. Confidence is the key. I've been in many interviewing situations, and all I can...

    Adhesive wear in two rubbing teflon hoses

    Hello, I was hoping someone could lead me to information regarding what I believe is called "homogenous adhesive wear". It's the tendancy for a material rubbing up against a component of the same material to wear and chafe faster than if two different materials were wearing. This is most...

    Explosion-Proof fan manufactures/suppliers

    We discovered that the fan we will be using to vent an enclosure was not rated for hazardous locations (explosion proof). This wasn't necessarily bad, because we just needed anything for testing purposes, but to be certified we will need an explosion-proof fan (it is, after all, venting out air...

    Ceramic 5 / Ferrite magnets -- possible leeching

    It's definitely rust-colored. The reddish-brown material can be seen clearly around the stem of the floats on the level sensors (the magnets are housed inside the floats). I have attached a photo showing the float and...

    Ceramic 5 / Ferrite magnets -- possible leeching

    I don't know what the resistivity of the deionized water was when we started the experiment, or even if that data was taken. I do know that this failure happened past the 10,000 hour mark (how far past, I don't know), so the magnets had plenty of exposure to the degradating environment. I was...

    Ceramic 5 / Ferrite magnets -- possible leeching

    We are using cermaic 5 magnets in liquid level sensors that are in heated deionized water, mixed with hydrogen gas. After a failure in the device, we noticed what appears to be rust around the magnets, and now we're trying to figure out if the rust (if that is what it is) came from particles in...
