What are the practical implications of line capacitance, and how can our equipment help manage these effects?
2025-08-13The practical implications of line capacitance are significant, especially in high-voltage and long-distance transmission. The primary effects are:
-
Charging Current: Capacitance causes a leading current to flow in the line even when there is no load. This can cause false tripping of protective relays.
-
Voltage Rise (Ferranti Effect): In long lines, the voltage at the receiving end can rise due to the charging current, potentially damaging sensitive equipment.
-
Reactive Power: Line capacitance generates reactive power, which must be managed to maintain overall system stability.
Our equipment plays a fundamental role in laying the groundwork for a stable system. While external compensators are needed to actively manage these effects, our tools ensure that the line's foundational parameters—such as conductor tension, spacing, and clearance—are set correctly from the start. A line constructed with our reliable and precise equipment provides a predictable platform for a stable electrical grid. By offering a comprehensive range of tools for overhead line construction and maintenance, we help power companies build lines that are both efficient and resilient.
