|Keywords:||ELECTRICAL ENGINEERING;AUTOMATED -TEST EQUIPMENT;PROTECTIVE RELAYS;MICROCOMPUTER|
|Abstract:||An AUTOMATED TEST EQUIPMENT FOR PROTECTIVE RELAYS has been designed in this dissertation work. The motivation behind choosing this topic, lies in the importance of relay testing and the possibility of performing this time consuming, complicated task with the help of a microcomputer. Accurate and thorough testing of relays is very essential to ensure that the protective gear always operates reliably on fault* aJ A microcomputer supported data acquisition system has been used to test basic static (electro.nic) relay circuits. Programs have been written in advanced BASIC to evaluate the performance of various relays under steady state and dynamic conditions. Over voltage, differential, directional, impedance and the admittance relays have been thoroughly tested in the labor-atory and their operating characteristics (static and dynamic) displayed on the C.R.T, screen. The tests are highly automated, with a minimum of manual intervention required. It is sugges-ted that this microcomputer based test system would lead to an economic, more, efficient less time consuming and reliable testing of relays, as compared to the conventi-onal methods used. An ARTIFICIAL TRANSMISSION LIKE used for dynamic testing of relays is very expensive and complicated. As against this$ dynamic testing by this automated test system would be much cheaper# easier and flexible as well,|
