CHAPTER I--FEDERAL COMMUNICATIONS COMMISSION
PART 15_RADIO FREQUENCY DEVICES--Table of Contents
Subpart B_Unintentional Radiators
Sec. 15.113 Power line carrier systems.
Power line carrier systems, as defined in Sec. 15.3(t), are subject
only to the following requirements:
(a) A power utility operating a power line carrier system shall
submit the details of all existing systems plus any proposed new systems
or changes to existing systems to an industry-operated entity as set
forth in Sec. 90.63(g) of this chapter. No notification to the FCC is
(b) The operating parameters of a power line carrier system
(particularly the frequency) shall be selected to achieve the highest
practical degree of compatibility with authorized or licensed users of
the radio spectrum. The signals from this operation shall be contained
within the frequency band 9 kHz to 490 kHz. A power line carrier system
shall operate on an unprotected, non-interference basis in accordance
with Sec. 15.5 of this part. If harmful interference occurs, the
electric power utility shall discontinue use or adjust its power line
carrier operation, as required, to remedy the interference. Particular
attention should be paid to the possibility of interference to Loran C
operations at 100 kHz.
(c) Power line carrier system apparatus shall be operated with the
minimum power possible to accomplish the desired purpose. No equipment
authorization is required.
(d) The best engineering principles shall be used in the generation
of radio frequency currents by power line carrier systems to guard
against harmful interference to authorized radio users, particularly on
the fundamental and harmonic frequencies.
(e) Power line carrier system apparatus shall conform to such
engineering standards as may be promulgated by the Commission. In
addition, such systems should adhere to industry approved standards
designed to enhance the use of power line carrier systems.
(f) The provisions of this section apply only to systems operated by
a power utility for general supervision of the power system and do not
permit operation on electric lines which connect the distribution
substation to the customer or house wiring. Such operation can be
conducted under the other provisions of this part.
