B. Power Frequencies
Power frequencies refer to 50 or 60 Hz signals, and their harmonics, that can be traced
without the use of a transmitter.
60: Best for general locating of passive power.
60H (high harmonic): If the 60 choice appears to be responding slowly, or poorly, then
60H is the second choice for locating of passive power.
60L (low harmonic): Third choice for passive power locating. May be used when 60 or
60L is weak or erratic. 60L may be the best choice when locating primary power cables.
120 Hz: Used for locating rectified AC power signals, often found on pipelines using
impressed current cathodic protection.
