<p>The method involves connecting a contact wire with a main power supply of public transportation, where the main power supply is connected with a public network. Supplied current from the public network into the main power supply is measured, and maximum recovered current from the contact wire in the main power supply is calculated from sum of maximum recovery lines of substations. Difference is determined from the supplied current and the recovered current by a controller, where recovery takes place in the main power supply during negative result over the controller.</p> |
