Harmonics Mode; Phase-To-Neutral Voltage Harmonics - AEMC PowerPad III 8336 User Manual

5.2 HARMONICS MODE

The Harmonics mode displays a representation of the harmonic levels of the voltage, current, and apparent power, order
by order. It can be used to determine the harmonic currents produced by nonlinear loads, and analyze problems caused
by harmonics according to their order (overheating of neutrals, conductors, motors, and so on).
● V - Phase-to-neutral voltage
● A - Harmonics of the current
● S - Apparent power of the harmonics
● U - Phase-to-phase voltage harmonics
● The and

5.2.1 PHASE-TO-NEUTRAL VOLTAGE HARMONICS

The V sub-menu displays the harmonics of the phase-to-neutral voltage only for sources having a neutral.
NOTE: The choice of curves to be displayed depends on the type of connection (see § 4.1.4):
● Single-phase, 2-wire: no choice (L1)
● Single-phase, 3-wire: L1, N
● Split-phase, 3-wire: 2L, L1, L2
● Split-phase, 4-wire: 2L, L1, L2, N
● 3-phase, 4-wire: 3L, L1, L2, L3, -,+
● 3-phase, 5-wire: 3L, L1, L2, L3, N, -,+
The examples shown in the following sections were obtained with a 5-wire 3-phase connection.
