The parameter ‘DefDirMode’ determines the response at the end
of the definitive time. It can be set to be either directional (in
tripping direction) or non-directional (see Fig. 3.5.31.8).
Note:
There is still a definitive zone even using the overcurrent
starter (OC), but only with respect to the parameters ‘Delay
(Def)’ and ‘DefDirMode’.
3.5.31.5. Back-up overcurrent unit
(O/C Back-up Protection)
(see Section 4.8.4.)
The settings for the back-up overcurrent unit are made via the
sub-menu ‘O/C BACK-UP PROTECTION’. The setting of the
parameter ‘I O/C’ determines the pick-up level, which can be
chosen in steps of 0.1 IN between 0 and 10 IN. The associated
time delay is set in steps of 0.1 s between 0 and 10 s by means
of the parameter ‘Delay O/C’.The pick-up signal of the overcurrent unit is also used by the
STUB protection. If the function is being used for this purpose,
i.e. the binary I/P ‘Isol open’ is at logical ‘1’, the tripping time is
fixed at 25 ms.
3.5.31.6. V.t. supervision
(see Section 4.8.3.)
The parameters for setting the v.t. supervision function are located in the sub-menu ‘V.T. SUPERVISON’. One of four different operating modes can be chosen using ‘VTSupMode’. The
function processes zero and negative-sequence components,
which are either used on their own ('ZeroSeq’ and ‘NegSeq') or
combined ('Zero*NegSeq’ and ‘Spec').The four pick-up values are the settings of the parameters
‘U0min VTSup’, ‘U2min VTSup’, ‘I0min VTSup’ and ‘I2min VTSup’.
They can be set between 0 and 2 UN (or IN) in steps of 0.01. The
basic settings are 0.2 UN for the voltage and 0.07 IN for the
current.
Only the ‘NegSeq’ or ‘Spec’ options are available in ungrounded
systems.
Upon operating, the v.t. supervision function is normally required
to immediately block the distance protection function (see
Section 4.8.5.2.). Provision is made, however, for blocking the
distance function after a delay of 12 s by setting the parameter
‘VTSupBlkDel’. This parameter is normally set in cases where
only the overcurrent starters are in use.If the v.t. supervision function remains picked up for longer than
12 s, it resets only after a delay (1 s). Should a fault give rise to
zero or negative-sequence current components, it resets immediately.
The parameter ‘VTSupDebDel’ (deblocking) enables the reset
delay to be continuously enabled regardless of current.
