A field comparison of RI and TVI instrumentation

Many different types of instruments are presently being used for the measurement of radio noise produced by power transmission lines. Different characteristics prevent a direct comparison of data obtained from various meters. A means of translating data to a common base for comparison is highly desirable. With this end in mind, a field study was performed on several types of meter in common use today. Results indicate that a satisfactory agreement between meters can be achieved for low frequency (radio broadcast band) measurements. For higher frequencies (television broadcast bands) correlation is less than satisfactory.
