The TSRDF is a control module, which can be used as a control element of a transformer switching relay when it is used in combination with external thyristors or semiconductor relays in a three-phase current supply. With the TSRDF switching of three-phase transformers over 50 A or frequently switching of three-phase transformers are possible. The soft starting procedure enables it to switch on one three-phase transformer in no-load-state or a loaded state without inrush current. With the soft starting procedure the inrush current is avoided, not only reduced.
