Ips Interface Protections - ABB SACE Tmax XT5 Operation And Maintenance Manual

3 - IPS Interface protections

Description The IPS Interface protection function allows faults to be managed in installations which are able to function
Protection 59.S1 [ANSI 59S1] The protection sends a TRIP command if the maximum mean value of the three line-to-line voltages,
Protection V DIR [ANSI 27VD] If the positive sequence measured by the Trip unit exceeds or falls below threshold Upos (depending on the
Protection V INV [ANSI 59VI] If the negative sequence measured by the Trip unit exceeds or falls below threshold Uneg, the corresponding

supply, e.g. caused by a fault on the MV voltage side.
The function is available for all the Ekip Hi-Touch Trip units.
All the parameters and measurements of the function are available via Ekip Connect; however, the Trip unit
allows protection 59 S1, V DIR, V INV and control thresholds Voltage stability, Frequency stability and F W1
