Teleprotection Module
Power Utility Module for Megaplex
Megaplex-4 Distance Teleprotection Module for power utilities
Features include:
4 110 VDC/220 VDC inputs and 8 outputs, galvanically isolated with high EMC
immunity for harsh environments
Ultralow end-to-end propagation delay for commands and automation
1+1 path protection with less than 10 msec recovery time
Secured and reliable end-to-end command transmission
Unidirectional broadcast for Automation commands
T-line support
The RAD Megaplex TP ( Teleprotection ) module offers ultralow end-to-end
propagation delay for immediate delivery of teleprotection commands and
automation, from protective relay/contact transfer to remote-end power utility
substations.
Megaplex-4 with its TP ( Teleprotection ) modules delivers teleprotection
commands and automation with mission critical accuracy over dedicated fiber, TDM
or IP, to help central control better manage the power grid load and to protect
termination and transformation equipment from severe damages resulting from
faulty high-voltage lines.
The TP ( Teleprotection ) module supports up to 4 command/automation
inputs and 8 outputs, enabling teleprotection equipment to utilize the advanced
transport capabilities offered by Megaplex.
Teleprotection commands can be locally output or be carried to a peer card/ RAD
Megaplex unit over TDM/SDH or packet switch network. Up to 4 commands can be
carried over a single DS0.
The teleprotection command and automation is triggered by 220 VDC or 110 VDC
input signal to the TP module.
The teleprotection module is also used for the automation processes by exchange
of data between the relay protection devices and the control center, thus
allowing for uninterruptable power supply throughout the grid when fault occurs.
Megaplex’s advanced carrier Ethernet and pseudowire capabilities guarantee the
performance levels required when migrating to packet networks with hard QoS, as
well as robust latency and jitter protection.
The RAD Megaplex TP ( Teleprotection ) module operates in conjunction with other
Megaplex modules catering for a variety of interfaces, such as voice, high
speed, low speed and others, to provide any possible service needed in a
substation.
