  "heading": "Automatic scheme against voltage collapse",
  "text": "1. The automatic scheme against voltage collapse of the system defence plan may include one or more of the following schemes, depending on the results of a TSO's assessment of system security:\n(a) a scheme for low voltage demand disconnection according to Article 19(2) of Regulation (EU) 2016/1388;\n(b) a blocking scheme for on load tap changer according to Article 19(3) of Regulation (EU) 2016/1388; and\n(c) system protection schemes for voltage management.\n2. Unless the assessment pursuant to paragraph 1 demonstrates that implementing a blocking scheme for on load tap changer is not necessary to prevent a voltage collapse in the TSO control area, the TSO shall establish the conditions under which the on load tap changer shall block according to Article 19(3) of Regulation (EU) 2016/1388, including at least:\n(a) the blocking method (local or remote from control room);\n(b) the voltage level threshold at the connection point;\n(c) the flow direction of reactive power; and\n(d) the maximum lapse of time between the detection of the threshold and the blocking.",
