T2 Voltage drop T1 Automatic Transfer System With NSM unit for 36 kV Easergy T200 I automation systems are factory predefi ned. No on-site programming is required. b The automation systems can be switched on and off from the local operator panel and disabled using the confi gurator. b Switches can be controlled manually in the following circumstances: v automation system switched off v switch in local mode. Sectionaliser (SEC) The sectionaliser automation system opens the switch after a predefi ned number of faults (1 to 4) during the voltage dip in the reclosing cycle of the top circuit breaker. b The automation system counts the number of times a fault current followed by a voltage loss is detected. It sends an open order if: v the switch is closed v the fault has disappeared v the MV supply is absent. b The automation system is reset at the end of the execution time delay. Transfer switch (ACO 1/2) ACO: Automatic Change-Over The transfer switch automation system allows for the automatic control and management of power supply sources in the MV secondary distribution network. It is linked to voltage presence detectors VD23. Operating modes The operating mode is selected via the Easergy T200 I confi gurator. Semi-auto mode, SW1 < > SW2 When the voltage is lost on the channel that is in use, the automation system switches to the other channel after a time delay T1. The automation system returns no data unless there is a loss of voltage on the new channel. Semi-auto mode SW1 > SW2, (SW2 > SW1) The automation system only switches from channel 1 or 2 to the back-up channel. Auto-SW1 or Auto-SW2 mode After switching channels, the automation system switches back to the priority channel if the MV supply on that channel is restored. Switching sequence Switching takes place if the following conditions are met: b Automation system switched on b SW1 open/SW2 closed or SW1 closed/SW2 open b No “transfer interlock” b No “earthing switch” on the 2 channels b MV supply lost on the channel in use b MV supply present on the other channel b No fault current. The automation system switches back to the main channel in “AUTO” mode if: b The priority channel is open b The MV supply on the priority channel is correct for the time delay T2. The close order on the back-up channel is given once the opening of the channel in use is reported. Source transfer interlock A digital input can be used to prohibit the issuing of orders from the local operator panel, the automation system and the remote control supervisor. This input is generally connected to the downstream circuit breaker. 63
