Tips: Difference between three-phase isolation transformer wiring Dyn11 and Dyn0
- When the secondary side load of step up/down transformer is not asymmetrical, Dyn11 wring is smaller than that of Yyn0.
- Dyn11 wiring can improve the sensitivity of the transformer over-current relay protection device and simplify the wiring protection.
- Dyn11 wiring can improve the low-voltage side and the sensitivity of protection device, which is conducive to the selectivity of every level protection device and the expansion of feed radius.
- The secondary zero line current of Dyn11 wiring isolation transformer is not limited. This is a great advantage of Dyn11 wiring, but Yyn0 secondary zero line current is not allowed to exceed 25%.
- The primary winding of Dyn11 wring has the phase voltage three times larger than the one of Yyn0 and the current three times smaller, so Dyn11 wring is characterized by thinner wire diameter, larger turning number and more insulation inter-layer.
