Selection of Electrical Motor

Selection of Electrical Motor The primary technical consideration defining the motor choice for any particular application is the tong required by the load, especially the relationship between the maximum torque generated by the motor and the torque requirements for start-up and during acceleration periods. The duty/load cycle determines the thermal loading on the motor. One consideration … Read more

Reasons for High Commercial Losses

 Reasons for High Commercial Losses Consumers such as agricultural using load on HP basis, extend their load without obtaining proper sections. Meter reading may be taken wrong purposefully. Some consumers adopt wrong connection i.e., they use some energy bypassing the meter. Some consumers, stop the working of meter by mechanical jerks using powerful magnets to … Read more
