METHODS OF TESTING PROTECTIVE DEVICE USING COMPUTER

In this paper, the usual method of analysing of test set is briefly described and by comparison with automatic computerised method, this method is suggested. Merrits and limitations of each case are described and the reason of emphasises in using automatic & computerised approaches are explained. The most important difference between conventional and modern methods is that, the first one works manually. Whilst in the second, stages of test operation is automatic and the role of hunman is minimum. As a result, the reliability of manual method is low & the errors is of course high [1,2].
