3. INTRODUCTION TO THE
RELAY
The HF9024 relay provide comprehensive Voltage fault protection for utilities
networks, industrial plants and networks as well as for other applications where
Voltage protection is required.
In addition to its protective functions, each relay offers control and recording
features. They can be fully integrated to a control system so protection, control,
data acquisition and recording of faults, events and disturbances can be made
available.
The relay is equipped on the front panel with a liquid crystal display (LCD) with 2
x 16 back-lit alphanumerical characters, a tactile 7 button keypad (to access all
settings, clear alarms and read measurements) and 11 LEDs that indicate the
status of the relay.
In addition, the use of the RS485 communication port by using protocol mode
bus makes it possible to read, reinitialize and change the settings of the relay, if
required, from a local or remote PC computer loaded with software.
Its flexibility of use, reduced maintenance requirements and ease of integration
allow the Relay to provide an adaptable solution for the problems of the
protection electric networks.
