N96 Digital Relays Specifications:
Manufacturing a wide range of CBCT (N96 Digital Relays), we have been
able to satisfy wide needs of our clients. Also termed as digital
relay, these refer to protective relays that uses an advanced
microprocessor for analyzing power system voltage and currents. These
are primarily used to detect faults in an electric power system and are
generally gray areas on which digital/numeric relay constitutes. These
apply A/D (analog/digital) conversion processes to the incoming
voltages and currents and analyze the A/D converter output to extract
as a minimum magnitude of the incoming quantity. These protective
relays use Fourier transformer concept (RMS and some form of averaging
are used in basic products). Fourier transform is commonly used to
extract the signal's phase angle relative to some reference, except in
the most basic applications.
Capable of applying advanced logic this equipment is highly in demand. It also analyzes:
Whether the relay should trip or restrain from tripping based on
current and/or voltage magnitude (and angle in some applications)
Complex parameters set by the user
Relay contact inputs
Timing and order of event sequences
Some of the features of these digital relays are:
Being user configurable at a level, this relay can be used for
changing front panel switches or moving of jumpers on a circuit board
Advanced event recording include some means for the user to see the
timing of key logic decisions, relay I/O (input/output) changes, and to
finding an oscillographic fashion at least the fundamental frequency
component of the incoming AC waveform
Relay possess an extensive collection of settings, beyond what can be
entered via front panel knobs and dials. These settings are the
transferred to the relay via an interface with a PC (personal
computer), which is used to collect event reports from the relay.
Advanced metering and communication protocol ports available in
modern versions of digital relay which allows the relay to become a
focal point in a SCADA system
