UFLS-1 Numerical Under Frequency Load Shedding Protection Scheme

  The Numerical UFLS-1 Protection Scheme is to be installed at the existing and new bulk/ primary substations for improving the power systemperformance with UFLS function.The GD8 interface unit acts as local HMI, allowing operator to view and change scheme setting locally. It also implement some supervisionfunctions include Invalid Auto-switching Actions, Scheme setting surveillance and Time synchronization etc..

NAS-1 Numerical Auto-switching Scheme

  The Numerical Auto-switching (NAS) Scheme is designed to service the bus-coupler & bus-section & Interconnector auto-switching scheme at the 6--132kV bulk/ primary substations for improving the performance.The GD8 interface unit acts as local panel HMI, allowing operator to view and change scheme setting locally. It also implement somesupervision functions include Invalid Auto-switching Actions, Scheme setting surveillance and Time synchronization

Mini-IPAC Integrated Protection and Control System

  The Mini-iPAC protection system comprises a separate set of relay on each feeder / capacitor bank circuit for trip circuit supervision, blocking, indications and alarms functions, and makes up of a system via GD8 and communication network.

DAF－120KL Fiber-Optic Transceiver

  Low cost Fiber-Optic Communication,Use data from 0-40kbps for a full-duplex serial link with up to 5 kilometers via multi-mode fiber.

  Easy Application,Plug transceiver directly onto a standard 9-pin serial connector(DB-9). No special mounting is required.

  Communication Mode Selection,Changes point to point communication mode to ring communication mode via jumpers.

GD8 Graphic Display, Operation Control & Remote Communication

  GD8 graphic communicating controller is an industrial graphic display controller designed for operation in rugged environment of power
  substations and power plants for protection, control and monitor application. It uses the industrial CMOS system-on-chip design and operation system based on IEC standards and high voltage harsh environment.
