Reactive Power Compensation Capacitors Bulging or Exploding Before Their Design Lifespan
2026年09月17日 16時10分45秒

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.

Overheated Neutral Wire and Neutral Current Exceeding Phase Current: What Are the Causes?
2026年09月17日 15時44分48秒

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.

5 Signs of a Weak Signal on a Spectrum Analyzer
2026年09月17日 09時02分30秒

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.
