Voltage Advanced Protections - ABB SACE Emax 2 Manual

4 - Voltage Advanced protections

List
The Advanced Voltage protections, available by default for the Ekip G Touch and Ekip G Hi-Touch models and configurable in the remaining models
as additional SW package, are:
Name Type of protection
S(V) Short-circuit with voltammetric control
S2(V) Short-circuit with voltammetric control
(1)
RV Residual voltage
(2)
Further details about the protections are given in document 1SDH001330R1002.
(1)
S2(V) protection is not available by default with Ekip G Touch. However, it can be integrated by requesting the relative SW package
(2)
available for 4P or 3P circuit-breakers configured with external neutral voltage
(3)
Block configuration available via Ekip Connect

S(V) protection: in the Linear mode, the current trip threshold for voltage values between Ul and Uh is calculated by performing linear interpolation
between thresholds Uh and I20 (first point of the line) and Ul and Ks * I20 (second point of the line). I

(8)
S2(V) protection: in the Linear mode, the current trip threshold for voltage values between Ul2 and Uh2 is calculated by performing linear
interpolation between thresholds Uh2 and I21 (first point of the line) and Ul2 and Ks2 * I21 (second point of the line). I

(9) the threshold Ks setting must ensure the following limitation: Ks * I20 ≥ 0.6 In; parameter Uh is available in the Linear mode; the setting must
comply with the following limitation: Uh > Ul
(10) the threshold Ks2 setting must ensure the following limitation: Ks2 * I21 ≥ 0.6 In; parameter Uh2 is available in the Linear mode; the setting must
comply with the following limitation: Uh2 > Ul2
