Transmission systems are at the heart of the power network and their availability is essential to the reliability of the system. Monitoring the line can help the owner to optimise its maintenance programme to ensure that work on the line is correctly targetted at the most urgent issues. The XC-2100E will allow the user to identify and locate events on the line, whether it is AC or DC, overhead, underground or a combination of the two. The most urgent issue on the line is a fault, but its integrity and operation may also be affected by the effects of lightning and deterioration in the performance of the circuit breaker, both of which can be monitored by this equipment. When a fault does occur, it can be difficult to locate, particularly on long remote lines. Conventional fault locators work on the principle of measuring the impedance of the loop through which the fault current flows. In most cases, this includes a return path through the ground for which knowledge of the actual impedance is hard to obtain and is often estimated, leading to inaccuracies in the measurement of the distance to the fault. By utilising travelling waves, created when the fault occurs, the XC-2100E can measure the fault position independently of impedance and identify the fault point much more accurately.
