STS Family has the facility to test not conventional CT, VT, Merging Unit (MU), by the IEC 61850-9-2 (SV) protocol.
STS Family generates current or voltage and injects these quantities into primary side of the CT or VT under test.
STS Family then reads the data from the network using its Ethernet port (Sample Values) in order to perform a variety
of different tests, as CT ratio and polarity up to 800 A or up to 2000 A (with BUX 2000) or 3000 A (with BUX 3000). It is
also possible to check the VT ratio and polarity, up to 2 kV. Test of MU.
