Calculation of Current Condition Single-core M.V.
CALCULATION OF CURRENT CONDITION BASED ON NTP-IEC 60502-2 Annex B
Maximum conductor temperature: 90°C.
Ambient air temperature : 30°C.
Ground temperature : 20°C.
Depth of laying : 0,8 m.
Thermal resistivity of soil : 1,5 K.m/W.
Screens bonded at both ends.
In the case of different conditions, the correction factors indicated by this standard must be applied.
