  • SF6-Air Charging Quantitative - wilcokats.nl

    SF6-Air Charging Quantitative For Ecr, cont 1, the quantitative value of the maximum tolerable contamination level depends on the choice of the acceptance level X for which we will take the value X = 2% (A1.9) This is a conservative lower limit in that it is much lower than the statistical scatter of about 3 to 5% within which functional performance can be assessed

  • SF6 Air Sensor Charging Siemens - wilcokats.nl

    SF6 Air Sensor Charging Siemens. Under normal load conditions, the vector sum of the three phase currents is near zero. It is not exactly zero as the system capacitive charging current of the load circuit is non-zero. The three phase cable charging currents sum to a zero-sequence current, typically under 1A for a [email protected]
