SEECO SENSE digital current and voltage sensor products function as data
collection devices (monitoring insulators) and are used to generate
current and voltage outputs in metering, relaying and fault detection
applications. Using next generation technology and a patented design,
they provide a more efficient and cost effective method of monitoring than
is currently available from conventional instrument transformers or
Compared to conventional
oil-filled transformers, SEECO SENSE
units are extremely light weight, with a small footprint and compact size,
facilitating use in stations or on pole structures where space or mounting
applications are restricted.
SEECO SENSE units are available
in current-only, voltage-only, and combination current and voltage
configurations. Ratings range from 7.5 - 500 kV, with current
ratings of 600, 1200, and 2000 amp, and fault ratings of 3000, 6000 and
Metering Accuracy - Type CS current sensors exceed
IEEE class 0.3 accuracy standards for revenue metering. CS current sensors
have broad dynamic metering ranges with virtually no degradation of
accuracy at input current values less
than the rated current. Accuracies are perfectly linear down to 1%
of rated current.
Zero Environmental Burden -
Insulation is maintained without the use of SF6, Nitrogen, oil, or other
harmful dielectrics. No special handling procedures are required,
and no hazardous materials to dispose.
Safety - No risk of catastrophic
failure from open current output loops and/or shorted voltage outputs. No need to short the current output.
Light Weight - Using composite (polymer) insulators makes the units extremely light and easy to
work with, typically less than 10% of the weight of traditional oil filled
devices. Mounting structure require-ments are reduced, as are
Mounting Flexibility - The
combination of light weight, small footprint, and oil-less design provides
unlimited mounting orientations on substation or pole structures.
Other Advantages - No current
transformer saturation or potential transformer Ferro resonance.
