6.1. Current sensors
The sensors are designed for optimal adaptation to the
technology of current digital equipment. The protection,
metering and control units for these sensors operate with
the same algorithms and have the same consistency as
conventional devices, adding more advanced algorithms
and functions.
Main advantages derived from the use of sensor based
systems:
1. Low volume.
The decreased power consumption of
these transformers enables drastic reduction of their
volume.
2. Improved accuracy.
Signal acquisition is much more
accurate due to high transformation ratios.
3. Wide range.
It is not necessary to replace the sensors
with others with higher ratios when the power of the
installation is increased.
4. Greater safety.
Open-air live parts are eliminated to
enhance personnel safety.
5. Greater reliability.
Comprehensive insulation of the
entire installation provides greater levels of protection
against external agents.
6. Easy maintenance.
It is not necessary to disconnect
the sensors when the cable or cubicle is being tested.
