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

Một đỉnh bất thường xuất hiện trên màn hình Máy phân tích phổ chưa thể xác định ngay nguồn nhiễu nằm ở đâu. Đỉnh này có thể xuất phát từ nguồn điện, mạch số tốc độ cao, bộ nguồn chuyển mạch, thiết bị vô tuyến hoặc một nguồn phát xạ nằm gần hệ thống.

When testing a radio system, a low-level signal on a Spectrum Analyzer does not necessarily mean that the transmitter is weak. The power level measured at the analyzer input depends on many factors along the entire signal path, including cables, connectors, filters, splitters, amplifiers, antennas, and the transmission environment.
