... Speaker Matching: Use the output tap which most nearly equals the total speaker impedance. If the load impedance falls between two output terminal values, favor the terminal of lower impedance. 70 Volt Line: The 70 volt distribution system permits connection to a large number of speakers, each to op ...

3-phase short-circuit current (Isc) at any point within a LV installation
... A formula which makes this deduction and at the same time converts the impedance to an equivalent value at LV is given, as follows: Zs = impedance of the MV voltage network, expessed in milli-ohms Uo = phase-to-phase no-load LV voltage, expressed in volts ...

TRANSMISSION LINES
... SWR is not an indication of transmission line efficiency. If you have low transmission system losses, high SWRs can be tolerated, with a transmatch or utilizing a low matched loss transmission line. If you have high attenuation from line, connectors or devices, you need to tightly control SWR. ...

... Similarly the formula is the same as Pythagorean Theorem used to find the hypotenuse of a triangle. This will be discussed later as to why. Another thing to take note is the impedance of a resistor and a capacitor with this formula. A perfect resistor has no reactance because it only resists current ...
