but if your on-coming 3-phase generator runs at a freq even SLIGHTLY out of phase with the online system, you'll see a LARGE voltage across the switch/breaker you are closing. As there is usually hundreds or even thousands of amps available, closing 180 deg out of phase can turn a 1 ton circuit breaker into a projectile

@PureEvilPie Little mistake in alignment makes lever in wall go boom

A 'sychro-scope' has an analog meter and a pair of 'sync lamps' connected across the online and oncoming behind an isolation xfrm set. When the voltage is 'in sync' the lamps go off

when the sources go out of phase, the lamps come on get brightest at 180, then dim again

lights are out? close breaker

Maybe thats why the two ohases we measured yesterday were at 380V

yup

When they should've been at zero

Small desync in the circuit breaker

because two phase of the same line witll always vary by 120 deg

Generator

Fhck

most simulators pass at least one phase of three through a phase shift-cirucit so that on phase + the shifted phase gives a new voltage based on the amount of shift

that's how a VFD works

>people live on hope

lol

people live on power

no power? no toliets, food, water... no hope

people live on potential, face resistance and need capacitance

or something like that

ah, potential (voltage) and inertia (current) = Power

@ManAnimal

yup time

LOL

1 - What's a lineup?

2 - A knife fight sounds fun if dangerous

3 - I hope the metal for those scissors was formed in a free range mine

lol; i'll pass. never bring a knife to a gun fight

Its clearly a knife fight animal

Its in the fucking sign

Dont bring a gun to an agreed upon knife fight

lol; u said it looked fun

wonder who mark is lol

ah
