  "text": "The characteristics of the main traction voltage systems (with the exception of over-voltages) are described in detail in the following table:\nNominal voltages and their acceptable limits in value and in duration.\nThe duration of voltages between U min1 and U min2 shall not exceed two minutes.\nThe duration of voltages between U max1 and U max2 shall not exceed five minutes.\nElectrification system\nLowest non-permanent voltage\nLowest permanent voltage\nNominal voltage\nHighest permanent voltage\nHighest non-permanent voltage\nU min2(V)\nU min1(V)\nU n(V)\nU max1(V)\nU max2(V)\nDC\n(mean values)\n400\n400\n600\n720\n800\n400\n500\n750\n900\n1 000\n1 000\n1 000\n1 500\n1 800\n1 950\n2 000\n2 000\n3 000\n3 600\n3 900\nAC\n(effective values)\n11 000\n12 000\n15 000\n17 250\n18 000\n17 500\n19 000\n25 000\n27 500\n29 000\nThe voltage of the collection bar in the substation including the line circuit breakers shall not exceed U max1,\nvoltages, in normal operating conditions, have to stay in the range between U min1 and U max2,\nwhen operating conditions are interrupted, voltages in the range U min1 to U min2 are acceptable.\nRelationship U max1/U max2\nEvery occurrence of U max2 must be followed by a level not exceeding U max1 for an indefinite duration.\nLowest tension of service\nWhen the operating conditions are interrupted, U max2 will be the lower voltage limit for the air breakers when trainsets can run.\nNote:\nValues recommended for under-voltage tripping.\nThe under-voltage breakers with fixed or adjustable trips can be adjusted for values between 85 % and 95 % of U min2.",
