TPT-200

Tele-Protection Signal Equipment

.TPT-200 gives fast, reliable and secure transmission of protection signals over all kind of communication media. A mix of analog, digital/optical and Ethernet transmission in any combination at the same time is supported, and multi-channels on various medias are hot backup each other.

Overview

  • Multiple transmission routes that provide fully redundant signaling capabilities If uninterrupted reliability is your primary goal, transmission route redundancy is absolutely essential.

  • Impulse Noise Compression technology. The impulse noise is on high voltage power line. The most serious disturbance can make false command accidentally on receiver and actuate protection relays. The DSP software is developed to check such impulse noise, increase the system security

  • Device addressing prevent unwanted interconnections between two equipments due to routing errors in digital networks and ensure that protection signals are received at the correct destination

  • Redundant power supply with hot standby

  • Various direct fiber optic connections between two TPT-200 devices, fiber optic to a multiplexer or to a PLC terminal

  • Coded tripping mode for 4 independent commands via analog transmission lines. Coded tripping utilizes two tones for the transmission of a protection command. This increases the transmission security anti tone interference.

  • High speed transmission time digital channel <3ms and analog channel <10ms

  • User friendly management system supports the remote access through Ethernet network.

  • Up to 24K sequence-of-events recording Support to record events of the teleprotection commands, system alarm and performance record per hour.
