midzyfazowy
Międzyfazowy is a term used in electrical engineering to describe quantities that involve two different phases of a polyphase system. It contrasts with quantities measured phase-to-neutral. In a three-phase system, międzypfazowy refers to line-to-line (between-phase) voltages and currents. For a balanced system with phase shifts of 120 degrees, the line-to-line voltage V_LL equals the square root of three times the phase-to-neutral voltage V_LN: V_LL = √3 · V_LN.
Commonly cited values reflect regional standards. For example, in many European systems a phase-to-neutral voltage is
Measurement and usage: międzypfazowy quantities are measured between two conductive phases, using a voltmeter or ammeter
Safety: handling between-phase connections involves higher and potentially more hazardous voltages than phase-to-neutral work. Proper lockout/tagout
Etymology and terminology: in Polish, the standard form is międzyfazowy; it is commonly translated as between-phase
