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. The conjunction of these High Voltage Dividers and
analyzers/recorders such as FLUKE/RPM, DRANETZ/BMI, YOKOGAWA, TEKTRONIX,
SQUARE D POWER LOGIC, HIOKI, NICOLET, COOPER POWER, IDTECH and
METROSONICS allow these 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 amplifiers, cable drivers and Fiber Optic
Transmission systems are available. |
