RELAYS 101 iPH

Merle Ashton

Protective Relay Technician Calculator for iPhone. All of the calculations of the RELAYS 101 for iPad version just missing the phasor drawings to fit the smaller iPhone screens. Symmetrical Components, Apparent Impedance, Phase-Phase calculations and vector addition and subtraction are now at your finger tips.
There are also pages to help you set-up relay tests for Phase-to-Phase faults (with no V0 and no I0), Phase-Ground fault relay tests and 3-Phase fault relay tests. There is a page for up to 6 vector additions (help you add Bus Diff phasors) and a PQS calculations page. An amazing amount of information in this APP. Your iPhone is now an essential tool for your relay testing tool box.
