e currents are removed from the differential signal then the spurious differential error signals are significantly reduced:


As seen from the example, removal of the zero-sequence current brings the currents almost to a perfect balance on this external fault. The remaining spurious differential signal results from line charging currents and the positive- and negative-sequence infeed coming from the low voltage side of the tapped transformers.
In order to cope with the differential error signal, a version of the relay without the zerosequence current removal would have to use:

ng systems can bethought of as the first generation synchronized measurementsystems because an implicit synchronization isachieved for phase angle comparison. The method is comparativelysimple as it only transmits zero crossing informationas a dc signal to the other end of the transmissionline.In 1983 Sun et. al. published a seminal paper describinga current differential relay system using fiber opticscommunication. The basic idea is to transmit phasesequence current information from one end to another usingPulse Period Modulation (PPM) method.

stations and distribution substations. Since transformer protection requirements vary depending on the application, users typically want only those functions which are needed for that specific application. To accommodate this customized functionality, the selection of transformer protective functions should be determined by users as opposed to manufacturers” the same as is done with discrete relay applications. This paper discusses user-selectable functionality that tailors the relay to specific applications. In addition, the use of programmable logic extends the benefit of digital multi..................[:=> Show Contents <=:]

can also be tested by closing a breaker on to a fault. Adequate oscillographic recording equipment should be available to study the specific features of interest. Such tests are however undertaken very occasionally only when a relatively new (type of protection is being tried out or when there is a special investigation on relay ^behaviour to be carried out.
Periodic Tests
Periodic check of relays at its actual settings is needed to ensure the following :
a) Healthiness of relays.
b) Operation of relay flags or visual indicators.

tage side of the taped transformers would create a differential signal and, most likely, result in a misoperation. Distance supervision can be used to cope with this problem. The distance element should be set to overreach securely all the line terminals including tapped lines. But at the same time, they should not reach to the low voltage terminals of the transformers (Figure 2).

This may create a problem, particularity if the transformers have a large power rating, are located very close to the substations, and at the same time the line is very long (Figure 3). In this difficult situati..................[:=> Show Contents <=:]
