It also discusses the relation between motor efficiency and motor load rate that the maximum point of motor efficiency is not at rated load,but at the load of 0.

This paper explained in brief the relation of three-phase asynchronous motor among efficiency, power factor, load rate and power and every power saving measures.

The paper gives the reason for motor low load ratio, advances some methods to solve it.

Capacity-to-load ratio is a key parameter to determine substation capacity.

By analyzing the load factor and unbalance factor of distribution transformer, the method of calculating and selecting the low voltage reactive power compensation capacity and compensation equipments, and the connection mode of capacitors were presented.

This paper analysed the characteristics of three phase inductive motor under single phase operation and deduced the relational expression of the current and load factor,which provided the theoretical basis for the single phase protection of motors.

This paper discusses the relationship between the temperature inside packaged substations and their load factor, structure, etc.

Taking into account of the cost of the transformer,the charge of the loss and the maintenance,the transformer s technical economic loading rate is deduced,which is higher than the traditional rate obtained from that the transformer s copper loss equals to the iron loss.
