    Why Does Switch Size Depend on Stored Energy & Inductance?

    When you disconnect a switch in a circuit of a given potential, it has the ability to transmit current directly through the air towards the nearest part of the switch. Since the switch is a conductive disconnecting device, the two sides of the circuit are in very close proximity to each other...

    Motor Accel Calcs: ETAP & Hand Calculations - Technologist in Training

    For anyone interested: Vm = Zm / (Zm + Zl) Where: Vm= Voltage during start-up Zm= Locked Rotor Impedance Zl= Impedance sum of source, line, xformer impedance *All values I used were per unit rectangular. As taken from the "Large Motors On Limited Capacity Transmission Lines" article...

    Can I produce electricity by using permanent magnets with no moving parts?

    I just spent 40 minutes writing the most accurate response in history... only to be logged out by the website and my response trashed. Suerbatica

    Problem with a electric circuit

    I studied Electrical, not Electronics, but I'll give it a whirl. What symbol is that, a Galvanometer? The one with the arrow inside the circle? Suer

    Problem with a electric circuit

    Just taking a quick browse, I have to get back to work, but first things first, try simplifying your impedances first. I always work in simplified equivalents. I also noticed your above formula is missing a lot of brackets, use this to force proper procedure out of your calculator. It does not...

    Motor Accel Calcs: ETAP & Hand Calculations - Technologist in Training

    Sorry for my late reply, I've been busy at work setting up this simulation. And I also made a quick reply earlier this week, but it was deleted by a moderator. I said or did something that violated the posting rules. ETAP - is the software package I am using to run the simulation, I cannot...

    Motor Accel Calcs: ETAP & Hand Calculations - Technologist in Training

    Hi everyone, I'm a Technologist in Training, except that I'm not getting much training. I have a tonne of questions regarding Motor Accel Simulation in ETAP. I'm hoping someone here might be kind enough to lend some insight, or point me to a place where I can find some. First off, has anyone...
