A Pole-Mounted Solar-Electric Array

“When Richard and Karen Perez launched Home Power in 1987, their mission was to change the way people generate and use energy, one rooftop at a time. And for two decades, we’ve continued to broadcast this message, loud and clear. Over the years,..”

Who would know better about Radio Frequency Interference and ElectroMagnetic Interference more than the Hams or Amateur Radio Community.

If they have to communicate effectively using limited resources, they have to deal with EMI/RFI effectively, While they build their equipment or combat Noise from other Machines and Installations nearby.

This problem needs more practical involvement and experimentation to learn, compared to learning something like Digital Electronics.

Equipment and Electricals like SMPS, AC/DC Drives, Motors, Solenoids and CFL Lamps are to be built/reinforced for low EMI/RFI emission/radiation.

Sensitive Medical Equipment like ECG or even a Aircraft can be seriously affected by Noise.

Surge Protection and Lightning Arrestors

Supplementary to EMI/RFI/EMC Immunity of an Equipment. Many Installations are subject to Highly Disruptive Electrical Environment not just EMI. Depending on the budget and the situation a solution has to be found. Sometimes a CVT or an Isolation Transformer can do a lot of good. Converting all Energy inputs to battery energy and having a Isolated Synthetic Sine Supply may be an expensive but good solution. Either way the devices that face the harsh environment have to be over rated along with these protections.

This is an educative and important guide for Electrical Equipment Safety. This can be also applied partially to Power Electronics and Home Energy Systems. Electronic Equipment also have to be maintained by Calibrating them and protecting them from environmental parameters like dust, grime, direct sunlight, moisture, humidity, sea wind (brine), corrosive fumes and chemicals. They should not be even placed near machines like a big lathe, sub-sonic or low frequency vibrations. Electrical Safety Testing Reference Guide Electrical Safety is a Serious Issue Electrical Safety in the workplace is the most important job of an electrical worker. No matter how much [Read More ....]
