Checking phase sequence of 3 phase supply
It is always important to ensure that the incoming 3-phase conductors have the correct phase sequence before connecting new equipment or before reconnecting motors after maintenance.
This might not be obvious by visual inspection, hence the need for a reliable tool. The two commonly used methods are the rotating phase-sequence meter or the static phase-sequence indicator.

Preparation and Benefits of Electrical Load Schedule
The load schedule, which should be done at the installation design stage, is determined through calculations. In some cases, this should be done with the future in mind, especially if there are foreseen additional loads. Preparing the schedule requires a list all the equipment or loads together and all associated ratings and parameters.

Wireless Power Transfer (WPT)
Nicola Tesla dreamed of finding a more efficient way than cables to transfer electricity. In 1891 in the Colorado Springs Lab Nicola Tesla managed to light some bulbs wirelessly placed 18 meter from the power source and this was the first time to successfully transfer electricity wirelessly. In this article we are discussing wireless power transfer principle, problems against its prevalence and its common applications.
