Neutralleidingen

Neutralleidingen, also known as neutral conductors or neutral wires, are a fundamental component of electrical power distribution systems. Their primary function is to provide a return path for electric current in AC (alternating current) circuits. In a typical three-phase AC system, which is commonly used for power transmission and distribution, neutralleidingen are essential for balancing the currents flowing through the phase conductors.

When electrical loads are connected between a phase conductor and the neutralleiding, current flows from the phase conductor, through the load, and back to the source via the neutralleiding. In a perfectly balanced three-phase system, where the loads on each phase are identical, the currents in the neutralleiding would theoretically sum to zero. However, in real-world scenarios, imbalances are common, leading to a current flowing in the neutralleiding. This current can be influenced by harmonic distortions as well.

The neutralleiding is typically connected to the ground at the power source, such as a transformer. This grounding serves a crucial safety purpose, helping to prevent dangerous voltage buildup in case of faults. While it carries current during normal operation, it is not intended to be a path for fault current to personnel. Proper insulation and identification of neutralleidingen are critical for safe electrical installations and maintenance. The color coding for neutralleidingen can vary by region, but a common convention is blue.
