high-voltageswitchgear Liquefaction System for middle voltages

Sep 26, 2013IEEE 141 divides system voltages into "voltage classes." Voltages 600 V and below are referred to as "low voltage," voltages of 600 V to 69 kV are referred to as "medium voltage," voltages of 69 kV to 230 kV are referred to as "high voltage," and voltages 230 kV to 1,100 kV are referred to as "extra high voltage"

  • IEC and IEEE Standards for High-Voltage Switchgear

    Standardization of the Ultra-High Voltage level ( 800 kV a.c.) The first step is the definition of rated voltage(s) and insulation levels by TC28 and TC8. Concerning high-voltage switchgear, IEC SC17A asked CIGRE SC A3 to set up a new working group to study technical requirements for UHV equipment.
