d. Formulas. i. Single phaseHU = kV x mA x sec. ii. 3 phase 6 pulseHU = kV x mA x sec x 1.35. 1.35 = rectification constant will give out 35 % more heat than single phase. More power in system. iii. 3 phase 12 pulseHU = kV x mA x sec x 1.41. Will give out 41% more heat than single phase. Objectives. Define thermionic emission.

Oct 01, 2015 · The circuit breaker for the SPD shall be located in the main panel or main switchboard as close as possible to the incoming feed for most effectiveness. For example, a 3 phase service with the incoming feed at the top of the panel bus, it shall be located in the 1, 3, 5 or the 2, 4, 6 pole position.

Kron reduce C(N x N) to C(3 x 3). Select the phase bundle that will have the greatest peak line charge value during a 60Hz cycle by successively placing maximum line-to-ground voltage Vmax on one phase, and – Vmax/2 on each of the other two phases. Usually, the phase with the largest diagonal term in C(3 by 3) will have the greatest .
