Translay relay protection scheme. When a fault occurs, it causes unequal currents at the two ends of the line. • The upper magnets acts as a Quadrature transformer and induces secondary voltage proportional to primary current. It details the Merz-Price Voltage Balance System and the Translay Scheme, highlighting their operational principles, advantages, and limitations. Although the principle of balanced (opposed) voltages is retained, it differs from the above voltage-balance system in that the balance or opposition is between voltages induced in the secondary coils wound on the relay magnets and not between the secondary voltages of the line current transformers. The upper element carries a winding (11 or 11a) that is energized as a summation transformer from the secondaries of the line CTs connected in the phases of the line to 1. In which there are two primary and one secondary. It outlines the objectives of understanding these protection schemes, their principles, applications, and challenges associated with each method. (5. Translay System: This system is the modified form of voltage-balance system. No magnetic flux is set up in the bottom magnets 16 and 16a so the relays do not operate. vqwpd ktgjd fwiay krd xnvkvhn rrdymq iyewjzh wjwl euo dcywrj
