Ross Engineering
Corporation has developed high voltage power line disturbance transducers
that are compact, portable and user friendly for observing or recording to
over 900KV PK. It utilizes state of the art Ross Engineering
Corporation wide band power class, high frequency (DC up to 10MHz) high
voltage dividers (VD's). In conjunction with DRANETZ, RPM, COOPER
POWER, TEXTRONIX, BMI, FLUKE, NICOLET, YOKOGAWA, IDTECH, SQUARE D and many
other analyzers/recorders these wide band VD's allow the recorders to
accurately monitor voltages beyond the recorder's normal limits.
These new systems are on
the leading edge of HARMONICS recording and are essential to accurately
analyze power "glitches" to frequencies up to 10MHz. The
previous technology that utilized frequency limited potential transformers
(PT'S) was not able to accurately sense the higher frequency harmonics and
transients needed to detect power quality problems that interfere with
computers and sensitive controls, as well as harmonics which can cause
overloads and equipment damage.
The Ross voltage dividers are available for
purchase or weekly rental. They are easily used by attaching a lead from
each phase of the HV power line directly to the top of each voltage
divider and grounding each base. The 20ft low voltage output coax cable is
connected to any suitable recorder, oscilloscope or computer. For greater
distances, matching amplifier, cable drivers and Fiber Optic Transmission
systems are available.
