transmission system. The bipole consists of two poles with components 1-4 making Pole
1 and components 5-8 making Pole 2. Let R1 through R8 represents the reliability of the
components 1 through 8.

a) Compute the general formula for the Pole Power Probability of Success, Rs(pole),
and Probability of Failure, Qs (pole) of the system. Rs (pole) represents reliability of
a successful operation of either Pole 1 or Pole 2, referred to as Pole Reliability.
b) Compute the general formula for the Bipole Power Probability of Success,
Rs(bipole), and Probability of Failure, Qs (bipole) of the system. Rs (bipole)
represents reliability of a successful operation of the entire bipole, referred to as
Bipole Reliability.
c) Compute the Probability of Success, Rs(pole), and Probability of Failure, Qs(pole) of
the system if the reliability of each of the components is 0.90 (90%).
d) Compute the Probability of Success, Rs(bipole), and Probability of Failure,
Qs(bipole) of the system if the reliability of each of the components is 0.90 (90%).
e) If the desired Pole Reliability, Rs(pole) (either Pole 1 or Pole 2) is 0.98 (98%),
assuming each component has the same reliability (R), what should the reliability of
each component be?
f) For (e) above, what is the Bipole Reliability, Rs(bipole), that is, both Pole 1 and Pole
2 are successful.
