3 Steps for Solving any Two Wattmeter Method Problem Part 2 (Electrical Power PE Exam)

How to solve every two method wattmeter problem on the Electrical Power PE Exam in three quick steps! In Part 2 of this series, we are going to show you: 1. How to draw the phasor diagram for both wattmeter 1 (W1) and wattmeter 2 (W2) depending on how each wattmeter is connected according to the three "RULES" from Part 1. The phasor diagrams will depend on which phases the positive (+) and negative (-) voltage polarity are connected to for wattmeter 1 (W1) and wattmeter 2 (W2). 2. How to easily derive the correct power angle (θ) for both wattmeter 1 (W1) and wattmeter 2 (W2) graphically using both of the phasor diagrams we set up. *Here's the trick! One of the line voltages being measured by either wattmeter 1 (W1) or wattmeter 2 (W2) depending on how they are connected will be NEGATIVE (CBA) SEQUENCE, and one will be positive (ABC) sequence. *Inside the cosine function in the power formula, one of the wattmeters will have θ MINUS thirty degrees while the other will have θ PLUS thirty degrees depending on how both wattmeters are connected: cos(θ-30º) cos(θ+30º) Click here to watch the next video (Part 3) in this series:    • 3 Steps for Solving any Two Wattmeter Meth...   __________________________________ 👉 Visit the full article on solving Two Method Wattmeter Problems: https://www.electricalpereview.com/3-... . **** PE EXAM *** 🔥 SUBSCRIBE for more videos on how to pass the NCEES® Electrical Power PE Exam!    / @electricalpereview   . 🚀 Ready to PASS the NCEES® Electrical Power PE Exam?
