The capacitor labels indicated a 10-year lifespan, yet after just two years of service, the casings began to bulge; some even exploded, accompanied by a popping sound and a burnt odor that permeated the electrical room. The maintenance team would install replacements, only for the exact same issue to recur a few months later. This cycle repeated multiple times before anyone finally questioned whether the failures were due to the capacitors reaching the end of their service life or because they were being subjected to conditions beyond their original design specifications.

According to balanced three-phase circuit theory, the neutral current should ideally be zero or negligible compared to the phase current. Yet, technicians frequently discover during inspections at electrical panels that the neutral wire is extremely hot, with measured neutral currents sometimes even exceeding the current in individual phase wires. This is neither a rare occurrence nor a measurement instrument error; rather, it indicates that the system's loads are non-linear, generating harmonics that traditional conductor sizing methods fail to account for
