can I connect 25KvA stepdown transformer(RYB-440V,UVW-240V)
to the output of 15KvA,3-phase online UPS(440V phase to
phase)please brief.
Generally in AC we consider voltage, frequency and phase sequence for parallel operation ... Can we parallel two DC battery chargers? If yes, then what precaution to be taken when we parallel two DC power?
