Radio influence voltage (RIV) generated on a transmission line conductor surface is not affected by Nearby radio receivers.
Radio influence voltage (RIV): A high-frequency voltage, generated on a transmission line conductor surface by any source of ionization current that appears at the terminals of electric-power apparatus or on power circuits.
It is affected by the following factors.
- Operating system voltage
- Corona discharge
- Atmospheric conditions like dust, rain
- Surface irregularity

Understanding Radio Influence Voltage (RIV)
Radio Influence Voltage (RIV) is the voltage generated on the surface of transmission line conductors, often as a result of electrical discharges. In analyzing the factors affecting RIV, it is crucial to discern which elements do not influence it.
Factors Affecting RIV
- System Voltage:
Higher system voltages can increase the likelihood of corona discharges, which can lead to elevated RIV levels.
- Corona Discharges:
These occur when the electric field around the conductor becomes strong enough to ionize the surrounding air, generating RIV. Thus, they directly influence RIV levels.
- Rain:
Rain can also affect RIV by changing the surface conditions of the conductors, potentially increasing the incidence of corona discharge.
Nearby Radio Receivers
- Unrelated Influence:
Nearby radio receivers do not impact the RIV generated on transmission line conductors. RIV is primarily a function of the electrical characteristics of the transmission line and the environmental conditions (like humidity and temperature), rather than external radio reception.
In summary, while system voltage, corona discharges, and rain can significantly affect RIV, nearby radio receivers are not a contributing factor. Understanding this distinction is vital for professionals in electrical engineering and transmission line maintenance.
