TPU-1 Thiết bị bảo vệ truyền cắt F85

The flexible design of TPU‑1 terminals allows the use of different types of modules depending on each application. This modularity allows TPU-1 terminals to manage one or two digital and/or analog channels. In cases where the TPU-1 terminal manages two channels, it can be configured to operate as two independent teleprotection terminals (in a single chassis). A TPU 1 terminal configured to work over analog channels is capable of transmitting and receiving up to four combined (single tone) or up to thirty two encoded (dual tone) commands. A TPU‑1 terminal configured to work over digital channels allows the two way transmission of up to eight teleprotection commands using digital lines with electrical or optical interface. The electrical interface can be 2 Mbit/s or 64 kbit/s according to Recommendation G.703 of the ITU-T, as well as 64 kbit/s, 56 kbit/s or 32 kbit/s according to Recommendations V.11 / X.21 and V.35 of the ITU-T. The optical interface of the TPU-1 can be for single-mode (2nd or 3rd windows) or for multimode (as per C37.94 standard). It is also available an IP interface that allows up to 8 commands to be transmitted through an IP/Ethernet network.
