EMF Shielding Inc was hired by Areva, who completed construction and testing of a power electronic STATCOM installation at the Glenbrook Substation in Stamford Connecticut, to perform a field surveys of the conducted and radiated interference from the installation.

Two surveys were performed; one with the equipment operating at the "maximum normal continuous output" and one with the equipment Off.

Three different tests were requested for each survey:
· Conducted Interference
· Radio Interference, and 
· Television Interference

A detailed report was submitted with data analysis and graphs showing all Radio and Television interference. Readings were calculated as an average of 3 scans per day with the STATCOM Off and On.

Conducted interference

· Using a Spectrum Analyzer, power line carrier noise measurements were made over the range 14-500 kHz with bandwidth and impedance termination corrections. 
· Measurements on the groundside of a 115kV CVT were made via a drain coil.

Radio Interference

· Radio noise measurements were in quasi-peak (QP) levels for AM band (535-1605 kHz) and peak levels for FM band (88-108MHz). 
· Three complete frequency scans were made at 4 selected locations around the perimeter of the property line.

Television Interference

· Television signal strength and noise measurements were in accordance with ANSI C63.2 over the range of 54 to 806 MHz.
· The measuring antenna was at a minimum height of 10 feet above ground when measurements were taken. 
· All data was reported at max bandwidth of 100 kHz.
