This is the apparent-power counterpart to tsiModuleLoadRatioW, expressing this module's current load as a percentage of its rated VA capacity rather than its rated wattage; the two can diverge when the connected load has a poor power factor, since VA accounts for both real and reactive power while watts captures only real power delivered. A module can show comfortable headroom on the watts-based ratio while actually approaching its VA-based limit if downstream equipment has a low power factor, since VA capacity is what typically constrains the physical wiring and transformer sizing. An admin who sees this ratio running noticeably higher than tsiModuleLoadRatioW on the same module would suspect the connected load has a poor power factor worth correcting.
