Protection V DIR [ANSI 27VD] If the positive sequence measured by the Trip unit exceeds or falls below threshold Upos (depending on
Protection V INV [ANSI 59VI] If the negative sequence measured by the Trip unit exceeds or falls below threshold Uneg, the

function thanks to the energy produced by renewable and local energy sources, especially the absence of
power 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 to be set, as described below.
