If the composite insulator is clean or even under dry contamination, its shed resistance is much larger than the shed capacitive reactance ( Rk>>(ωCk)1, Rk>> (ωCLk)1 and Rk>> (ωCEk)1 ).
If the composite insulator is clean or even under drycontamination, its shed resistance is much larger than the shedcapacitive reactance ( Rk>>(ωCk)1, Rk>> (ωCLk)1 and Rk>>(ωCEk)1 ).
