In many products used in the power distribution industry, when a transformer is initially connected to a source of AC voltage, a substantial surge of current called Transformer Inrush may occur. During out of phase STS transfers, a transient current larger than the transformer current can flow for several cycles, potentially resulting in circuit breaker trips and loss of critical load.
Our exclusive Dynamic Phase Compensation technology helps protect upstream sources and downstream critical loads from transformer
inrush currents by constantly monitoring the power and introducing an appropriate delay in switching. This delay significantly reduces inrush currents for out-of-phase transfers, preventing upstream tripping, and eliminating potential UPS overload.
LayerZero’s Dynamic Phase Compensated Transfer eliminates this inrush seen in traditional STS.
