17- The electromechanical breakdown depend on the type of the dielectric between two electrodes a- Right. b- Wrong 18- Basic Insulation Level (BIL) is related to the design consideration of the electric device, while Basic protection (BPL) level is related to protection level of the that device. a Right. Wrong. b- 19- As the voltage regulation increased, receiving end voltage will be reduced. Right. b- Wrong 20- We can be using Solar power generation field as a power factor and voltage profile enhancement in Distribution system. (aRight. b- Wrong. 21- From the general electrostatic theories, the field strength at breakdown is given by: a Eb = V/ do =0.6 [Y/ (€ o Er) ] 0.5. b- Eb V/ do = 0.6 [Y / (€ 0/Er )] 0.5. C- Eb V/ do = 0.6 [ Y/(Eo Er) 20.05. d- Eb V/ do = 0.6 [ Y/ (Eo Er) 10.5. 22- Consider plane electrodes with a solid insulator between them. Find the electric field strength at breakdown, if Young's modulus = 10000 (V.F/m2). and the relative permittivity is (36000 TT). If the…
