Example electric reading course.
This is an example of how we are working at a course called 'electrical reading course'which we are developing as an E-book and should soon be available on this site.
Active reactive and apparent power.
This is a small part of our pilot-E book; Active, reactive and apparent power which are important quantities within the Marine and offshore industry.The E-book explains motorcharacteristics related to energyconsumption,and energysaving by means of power factor correction.In order to save fuel, or to achieve loadreduction on cable's which are used at your ship in case you are already dealing with overloaded cables.In this cases you can extend the life span of your cables because they get less deteriorated.
