What measures should be taken to reduce the voltage drop of the secondary conductor of the voltage transformer?
To minimize the voltage drop in the secondary conductor of a potential transformer, several effective measures can be implemented. First, it is essential to install dedicated control cables for the energy meter’s secondary circuit. This ensures that the signal remains stable and accurate, reducing any unnecessary resistance. Second, increasing the cross-sectional area of the wire can significantly lower the resistance, which in turn reduces the voltage drop over long distances. Third, minimizing the number of series connections in the circuit helps prevent cumulative voltage loss. Each connection point introduces some resistance, so fewer connections mean less overall loss. Finally, using a voltage error compensator can actively adjust for any voltage deviations caused by the load or environmental factors, ensuring more precise measurements. These steps collectively help maintain the accuracy and reliability of the voltage transformer's secondary output, making them crucial for proper system performance.
