Induction circuit breaking
WebDC Dynamic Braking: It is commonly used for braking of single phase induction motors. With the help of a double pole double throw (dpdt) switch or tripple pole double throw … Web13 mei 2002 · Inductive circuits are more severe on switch contacts than resistive circuits because inductance opposes a change in current. The self-induced voltage that is set up by a rapidly collapsing magnetic field can be much higher than the normal supply voltage. This is because the rate of change of the decreasing current on break is very high.
