electrical degree การใช้

The 365-foot emergency antenna is 145.5 electrical degrees with an efficiency of about 343 mV / m / kW at 1 km.
There are some customers in downtown areas who get 120 / 208 volt service, since they actually are provided with 2 phases 120 electrical degrees apart.
Typical parameters determining synchronization are : voltage difference less than 5 %, frequency difference less than 0.2 Hz, and maximum phase angle between the sources of 5 electrical degrees.
Instead larger universal motors often have " compensation windings " in series with the motor, or sometimes inductively coupled, and placed at ninety electrical degrees to the main field axis.
A split-phase motor has a secondary startup winding that is 90 electrical degrees to the main winding, always centered directly between the poles of the main winding, and connected to the main winding by a set of electrical contacts.
