Wye Delta Starter

Wye Delta Starter

When the Starter Type parameter is set to Wye-Delta, the MX

is configured to operate an electro mechanical Wye-Delta (Star-Delta)

starter. When in Wye-Delta mode, all MX

motor and starter protective functions except bad SCR detection and power stack overload,

are available to provide full motor and starter protection.

A typical closed transition Wye-Delta starter schematic is shown in the figure below.
