Protection functions
The Ekip Hi-Touch trip unit has the following protection functions, which it shares with Ekip Touch:
– Overload (L – ANSI 49);
– Time-delayed overcurrent (S – ANSI 51 & 50TD);
– Thermal memory;
– Instantaneous overcurrent (I – ANSI 50);
– Closing on short-circuit (MCR);
– Earth fault (G – ANSI 51N & 50NTD);
– Earth fault on toroid (G ext – ANSI 51G & 50GTD)
– Neutral protection;
– Start-up function;
– Zone selectivity for functions S and G (ANSI 68);
– Current unbalance (IU – ANSI 46);
– Undervoltage (UV – ANSI 27);
– Overvoltage (OV – ANSI 59);
– Underfrequency (UF – ANSI 81L);
– Overfrequency (OF – ANSI 81H);
– Voltage unbalance (VU – ANSI 47);
– Residual current (Rc – ANSI 64 & 50NTD);
– Reverse active power (RP – ANSI 32R);
– Synchrocheck (SC – ANSI 25, optional);
– Cyclical direction of the phases (ANSI 47);
– Power factor (ANSI 78);
– Current thresholds;
– Power Controller function (optional).
The following protections are also available:
Second time-delayed overcurrent protection (S2 – ANSI 50TD): in addition to the standard protection
S, a second (excludible) time-constant protection is available that enables two independent thresholds to
be set in order to ensure precise selectivity, especially in highly critical conditions.
Second protection against earth fault (ANSI 50GTD/51G & 64REF): whereas with Ekip Touch the
user has to choose between implementation of the protection G by internal current sensors (calculating
the vector sum of the currents) or G ext external toroids (direct measurement of the earth fault current),
Ekip Hi-Touch offers the exclusive feature of simultaneous management of both configurations by two
independent earth fault protection curves. Owing to this characteristic, the trip unit is able to distinguish
a non-restricted earth fault and then activate the opening of Emax 2, from a restricted earth fault, and to
thus command the opening of the medium voltage circuit-breaker.
Another possible configuration is with the residual current protection replacing the Gext protection, whilst the
G protection remains active. The residual current protection is activated in the presence of the residual current
rating-plug and of the toroid.
