this paper represents the performance of a squirrel-cage high temperature superconducting induction/ synchronous motor (hts-ism) based on nonlinear electrical equivalent circuit. the structure of the hts-ism is the same as that of the squirrel-cage type induction machine, and the secondary windings are fabricated by the use of the hts wires. it has already been shown that based on the experimen...

Interconnected power system networks are multi loop structured. Settings determination of all over current and distance relays in such networks can be in different forms and complicated. The main problem is the determination of starting points i.e. the location of starting relays in the procedure for settings, which is referred to as break points. In this paper, a new approach based on graph th...

High Torque Low Current (HTLC) Starter is the new innovative motor soft starter system. This is a motor starting method for high inertia loads using a low voltage drive with input and output transformers to control motor torque and limit current when starting a medium/high voltage motor. The HTLC is a solution to motor starting problems where Direct on Line (DOL) or “Across the Line” starting i...
