Abstract :
BASIC insulation levels have been defined, and a list of proposed values has been determined by national committees charged with this responsibility. The purpose of this paper is to discuss some of the principles useful in selecting electrical equipment conforming to the requirements of that basic insulation level necessary to assure satisfactory service while operating within the voltage range and under the system conditions expected.
