Motor starting auto transformers for on-line starting of motors are simple and economical. Offering maximum starting acceleration and torque. auto transformer overcomes the two major limitations of on-line starters - high starting current and high starting torque.
The selection of a suitable starting method for a motor is becoming increasingly important as additional loads are added to existing utility and distribution systems. In the past, ample capacities were available in the utility networks to support the needs of industry. As well, the distribution systems of most North American industries were established during the industrial and technological boom years preceding the Second World War. In the 1990s, the viability for the construction of new electrical generation plants became prohibitive. With lower North American utility generating capacity and increased risks involved in the de-regulation of this utility, stability and voltage drop concerns have become very real issues that face all electrical power consumers.
