The metal halide lamp is a high energy electric lamp that produces visible light by an electric arc tube and it is a type of high-intensity discharge (HID) that contains a fused quartz and mixture of gases. These lamps inject noise into the smart-grid power line communications (PLC) network. This can have a strong and negative effect when using the PLC system to control the automatic switching of...
The mercury vapor lamp is the oldest high intensity discharge technology lamp that uses an electric arc, and comes in different shapes and designs. It creates a very bright light by using an arc through vaporized mercury in a high pressure tube. This lamp can cause unwanted interference to the smart-grid network or power line communications channel when connected to the channel’s wiring system. In...
The high pressure sodium lamp is a high energy outdoor light source that belongs to the high intensity discharge lamp family. It comes in different shapes and requires a ballast to start it. The high pressure sodium lamp is a source of interference to the power line communications channel as it injects noise when connected to the 220V mains. This paper investigates the influence of the high pressure...
The power-line communications channel (PLC) is one of the harsh and challenging channels due to heavy load and noise impairments. Sending and/or receiving of data bits over the PLC channel can be easily affected; therefore, several investigations have been conducted to illustrate interference effects over PLC where intermittent noise plays a major role in this type of communications channel. The in-building...
The fluorescent lamps or fluorescent tubes are low pressure mercury-vapor gas-discharge lamps that use fluorescence to produce visible light. These lamps inject noise into the power-line communications channel. This can have a detrimental effect on the power-line communication system. In this paper we investigate the effects when the fluorescent lamps with electronic ballasts are seen as noise sources...
LED (Light Emitting Diode) lamps have recently come on to the market as energy efficient alternatives to incandescent light bulbs. Although energy effective, they inject conductive noise into the power-line system. This can have a detrimental effect on the power-line communications channel. This paper investigates these effects when LED lamps are seen as noise sources on the power line. It shows that...
A number of measurements show the results of the harmonics and conducted emissions from “Energy-Savings” Compact Fluorescent Lamps (CFL) when connected to the power-line communications channel. Different CFL's from different manufacturers were investigated. The paper covers the CENELEC band, as well as the broadband communications channel: 150kHz–30MHz. The obtained results show the levels of harmonics...
The powerline channel is considered as a challenging channel due to the heavy load and noise impairments. In this paper we investigate an important type of measurement with regards to the powerline communications channel, where the low voltage wiring inside a house is considered as a receiving antenna for interference. Several types of measurements are presented using the corresponding broadband PLC...
