Introduction The PCS-902 offers comprehensive protection and control solutions for transmission lines with high-speed sub-cycle distance element. The PCS-902 is planned for application on overhead lines and underground cables with various voltage levels. These include series compensated, double- circuit, heavily loaded, feeble in feed (WI), short and long lines. It can meet the necessities of single-pole or three- pole tripping; it also provides single and/or three-pole auto- re-closing functions. The PCS-902(line distance relay) is appropriate for single and dual- breaker Uses Applications so long as optional dual CT inputs, dual breaker failure protections, and dual breaker auto-re-closing and dual synchronous-checks. Furthermore, the relay integrates the remote/ local control of circuit breaker, dis connector and earth switch. The PCS-902(line distance Relay) works on wide range of advanced patented tools, such as DPFC (Deviation Power Frequency Component) distance protec

PCS-9710 Remote Terminal Unit The PCS-9710 Remote Terminal Unit (abbreviated as RTU) adapts to all kinds of substations and power plants in high, middle and low voltage levels. It supports AC & DC analog sampling, configurable binary inputs and outputs (abbreviated as IO), programmable logic, etc. The PCS-9710 RTU is a microprocessor-controlled electronic device that interfaces objects in the physical world to one or multiple Network Control Center (abbreviated as NCC). It admits an object-oriented design with a combined software and hardware stages which supports the access with nearly all kinds of quick device (abbreviated as IED) of NR Electric and the third party. Functions      Flexible IO  configuration      Communication with IED      Communication with dispatching center or control center      Data calculation and synthesis      Operation record and query      Time synchronization      Remote debugging      Auto-diagnostic Fea

PCS-9705 Bay Control Unit (abbreviated as BCU) is used for bay level controlling and monitoring in power grid. It is suitable for application in Substation Automation System (abbreviated as SAS) with distributed control IEDs. PCS-9705 can be applied into SAS via Ethernet network in using NR private 103 protocol or IEC 61850-8-1. It can also send/receive Generic Object Oriented Substation Event (abbreviated as GOOSE) message in station level network. PCS-9705 is designed for controlling and monitoring switch-gears such as circuit breaker, dis connector, and earthing switch. Additionally, it supports tap changer control for transformer and shunt reactor. Features PCS-9705 adopts a fully closed chassis with a complete panel. Completely isolation for electronic and electrical system is provided. Back plug-in module structure is adopted. Electrical and electronic circuits are strictly separated to enhance EMC immunity performance. PCS-9705 adopts NR's new UAPC
