Technical data of product parameters

The ancillary unit requires no special maintenance. It should,
however, be checked regularly as is the case with all safety devices. This can take place according to the procedure given in TCCCR014 97197975-A01
Section 4.2.3.5.
The shaft grounding brush must be checked frequently and,
where necessary, cleaned and the spring pressure adjusted.
The contact resistance of the brush must be as low as possible
and above all constantFault-finding is limited to using the test procedures described in
Section 4.2.3.5. to determine whether the protection is functioning correctly. Faulty devices must be returned to the nearest
ABB office or agent or to ABB, Baden, Switzerland.When ordering accessories or spares always state the type designation and serial number of the protection device for which TCCCR014 97197975-A01
they are intended. Where several devices of the same type are
installed in a plant, the procurement of a spare unit is recommended.
Spares must be stored in a clean dry room at moderate temperatures. It is recommended that spare units be tested at the TCCCR014 97197975-A01
same time as routine testing is being carried out on those in operation.In the case of differential protection, the c.t’s must be connectedsuch that for a through-current, i.e. as during normal load conditions or an external fault, the currents flowing through theRE. 216 are in opposition thus producing zero differential currentProviding the c.t’s and v.t’s are connected as shown in Fig.
for directional protection functions (‘DirCurrentDT’,
‘DirCurrentInv’, ‘MinReactance’, ‘Power’, ‘Pole-Slip’, ‘UIfPQ’ and
‘MeasureModule’), the directional data give in Section 3 applies,
i.e. power transferred to the power system is assumed to be
positive and power consumed from the power system (reverse
power) to be negative. With the c.t. and v.t. circuit shown in Fig.
4.16, the setting for the reverse power function is entered as a
negative quantity.
