Page 14: Earth Ultrasensitive Device
Extremely inverse curve 3.2. Earth ultrasensitive device This functionality is available in both directional and non- directional ekor.rci and corresponds to a particular case of overcurrent detection for phase-to-earth faults. It is primarily used in networks with isolated neutral, resonant earthed neutral or on highly resistive soils, where the phase- to-earth fault current has a very small value.
Page 15: Presence/Absence Of Voltage
3.3. Presence/absence of voltage This function allows the detection of voltage presence or absence in those lines where the ekor.rci is installed. The metering is carried out by using the capacitive coupling of the cubicle bushings. Thus, conventional voltage transformer systems are not required.
Page 16: Non-Directional Earth Fault Indication
The fault detection is signalled locally through the ekor.rci display, or remotely through the communications or through one of the available outputs, by sending this signal to a remote control terminal.
Page 17 For the same fault, the capacitive return current in parallel lines can be higher than the rated magnitude set in ekor.rci, although there is not really any fault in its line. In order to avoid that, due to overcurrent detection, ekor.rci provides an incorrect fault detection, the presence of voltage is verified once the fault current has been detected.

General instructions Sensors ekor.rci 5.2. Vector sum/zero-sequence wiring (current) The wiring of the aforementioned sensors is performed in two different ways, depending on whether they have a zero-sequence toroidal current transformer installed or not. As a general rule, the zero-sequence transformer is used when the earth fault current is a value less than 10 % of the phase current rating.
Page 26: Voltage
In addition, to configure directional fault indication, on-off calibration is performed on the unit already installed in the cubicle, enabling the ekor.rci voltage metering unit to reach accuracy levels equivalent to a conventional voltage transformer.
