Verification of the Structure & the Safety Index about Voltage-sharing Ground Network
Dan Wu · Hubei Electric Power · 2011
The paper designs an unequal interval voltage-sharing ground network based on the ground network voltage-sharing theory.Through pratical test and calculation of the ground network parameter,some individual factors are found wrong.The practical test proves that the voltage-sharing effect of voltage-sharing ground network is very significant.The nets mesh potential are roughly the same,the difference between mesh potential and average potential is less than 2.67%,and the maximum mesh contact voltage difference is lower than that of long mesh or square mesh network about 40% or so;the requirement of the regulations is well met in safety indicators such as contact potential difference and the maximum step potential difference.
