INSULATION COORDINATION BASED ON IEC 60071-2 (1997)
The purpose of this code is to Compute the Basic Insulation Level (BIL) of an Electrical Installation.
STEP 1: DETERMINATION OF THE REPRESENTATIVE
OVERVOLTAGES (Urp)
STEP 2: DETERMINATION OF THE CO-ORDINATION WITHSTAND VOLTAGES (Ucw)
STEP 3: DETERMINATION OF THE REQUIRED WITHSTAND VOLTAGES (Urw)
STEP 4: CONVERSION TO WITHSTAND VOLTAGES NORMALIZED FOR RANGE I
AND RANGE 2
It is Important to emphasize that the computation I am about to bring about is for a grid/system that works at 60 HZ.
