Mitigating Harmonic Distortion for Reliable Communication Lines
This white paper explores how harmonic distortion from power systems generates interference on analog telephone lines, quantified by the Telephone Interference Factor (TIF). It details the origins and calculation of TIF, the impact of power quality on telecom systems, and how modern power quality recorders, such as those from Power Monitors, Inc., can measure and help address these issues. The paper emphasizes the importance of collaboration among power producers, telecom companies, and equipment manufacturers to reduce interference and maintain communication reliability.
Key topics include:
- Introduction to Telephone Interference
- Origins and Evolution of TIF
- Causes of Communication Line Interference
- Calculation of TIF
- Using ProVision for TIF Measurement
- Impact of Harmonics on Telecom Systems
- Mitigation Strategies and Industry Collaboration
Why utilities should care:
Understanding and measuring TIF enables proactive identification and mitigation of harmonic-induced interference, ensuring compliance, reducing customer complaints, and supporting the reliable operation of both power and communication infrastructures.
