The TS (TrafoSTART) is an electronic relay for the switching single-phase transformers. The magnetization of the transformer core is maintained in limits during energization. This transformer starting method totally eliminates inrush current with minimal start up time (from 0,06 s). The TrafoSTART is suitable for all kinds of transformers – EI, UI, C, toroidal, at al. Parallel connected transformers of different types can be connected to one TrafoSTART. The TrafoSTART is recommended for frequently switched transformers and for low-losses transformers with high working induction. The device is easily installed into the primary lead. The TrafoSTART can replace transformer contactor, when control input is used.
During startup, the transformer core is re-magnetized to opposite value of magnetization with exactly specified increment in each half period of the supply voltage. Magnetizing impulses are revised according to the primary voltage waveform. Such a principle ensures error-free operation without any transformer secondary load.

The 7SD610 relay is a differential protection relay suitable for all types of applications and incorporating all those functions required for differential protection of lines, cables, transformers and busbars. Transformers and compensation coils within the differential protection zone are protected by means of integrated functions, which were previously to be found only in transformer differential protection. It is also well-suited for complex applications such as series and parallel compensation of lines and cables.
It is designed to provide protection for all voltage levels and types of networks; two line ends may lie within the protection zone. The relay features very high-speed and phase-selective short-circuit measurement. The unit is thus suitable for single-phase and three-phase fault clearance.
Digital data communication for differential current measurement is effected via fiber-optic cables, networks or pilot wires connections, so that the line ends can be quite far apart.
