Innovation from RFL:
An essential part of any powerline carrier commissioning, or maintenance program requires verifying the efficient
transfer of power from the powerline carrier equipment to the transmission line. Previously this test required taking
the powerline carrier system out of service, and connecting SWR meters, and often, frequency selective voltme-
ters, in the switchyard, at the line tuning equipment. RFL Electronics Inc.’s Sequence of Events module now offers
a convenient, alternative to this testing method.
The RFL Sequence of Events option now offers the ability to locally, or remotely verify the transmitter reflected
power, as well as both the transmit, and receive signal levels. Besides providing instant channel status , this
feature provides the answer to the question, “which end of the line has the problem?” without even leaving the
office.
