Question

In Potier triangle, the Potier reactance drop is 22 volts per phase at full load current of 88 amps per phase. The potier resistance per phase is
1. 0.22 Ω
2. 0.25 Ω
3. 0.43 Ω
4. 0.7 Ω

Answer 1

Correct Answer - Option 2 : 0.25 Ω

In a Potier triangle method, the Potier resistance per phase is given by

R = Potier reactance drop per phase/full load current per phase

= 22/88 = 0.25
