3PE Calculator

设计和3相电（3PE）系统的配置。

This program provides the basic information for design and configuration of 3-phase electrical (3PE) systems. Depending on power consumption of the consumer (EM motor), the program provides information for selecting proper cable, fuses, current transformer (CT) for measurement purposes, contactors for operating with the load and motor protectors for over-current protection of the motors. The calculations are made for 3-phase asynchronous EM motors as consumers in the systems, but they can also be used and for any other type of 3-phase load consumer.
