Delta connection – Y-shaped arrangement of three-phase windings.
Star connection – Triangular arrangement of three-phase windings.
Bridge – Connecting two or more points in a circuit.
Overload – Device, connected in a circuit that trips the circuit when an excess
Motor windings are protected against abnormally high currents (overload) by
way of overload protection devices, normally in the starting circuit.
Overload settings depend on how the overload protection devices are
connected, i.e. in line or in phase.
Voltage measured between lines is the ______voltage (VL).
Voltage measured across a phase is the _______voltage (Vp)
Current flowing in a phase is the ______current (IP).
Current flowing in a line is a ______current (IL)
In a ______connected winding the phase current is the same as the line current.
The ______voltage in a star connected winding is lower than the line voltage.
In a delta connected winding the phase volts are equal to the ______volts.
The _________current in a delta connected winding is equal to the line current divided by the square root of 3.
