Overview

• The Lab-Volt 0.2 kW Protective Relaying Training System extends training in protective relaying beyond the operation and calibrations of individual relays into broader circuit applications.

  The system provides hands-on training at the system level in Generator Protection, Transformer Protection, and Induction Motor Protection.

Topic Coverage

• Common Electrical Modules
  Includes several modules that are part of the Lab-Volt 0.2 kW Electromechanical Training System, Model 8001, including: power supply, synchronous generator, induction motor, prime mover/dynamometer, resistive loads, voltmeters, ammeters, and others.
• Power System Modules, 3700 Series
  Includes training modules specifically designed for protective relaying and installations into the Lab-Volt EMS workstation. Modules include current transformers, voltage transformers, power transformers, source impedances, a transmission grid, and others.
• Protective Relaying Control System
  Includes two mobile racks for protective relay operation and storage, including a DC power supply, DC control relays for system studies, and an interconnection panel to facilitate connection of the protective relays to the target system.
• Protective Relays, 3800 Series
  Includes several protective relays mounted on a metal panel to facilitate installation in the Protective Relaying Control Station. Protective relays include undercurrent/overcurrent, undervoltage/overvoltage, synchronism check, underfrequency/overfrequency. phase balance, phase sequence, reverse power, and power factor.
• Additional and Optional Equipment
  Several optional modules can be added to the basic Protective Relaying Training System, including distribution busses, a generator ring bus, transmission, lines, distribution transformers, protective relay, and reactive loads.

Equipment Features

• Modular system approach allows
  • Selection of areas of interest for study
  • Equipment selection to match budgets
  • Set-up of complete power systems/generators feeding various devices such as transformers, transmission lines, and others
  • Progressive system enhancement
• Use of many modules from the Lab-Volt Electromechanical Training System (EMS), 8001 Series.
• Fault insertion capability for troubleshooting at the system level.
• All device connections are terminated with 4-mm safety banana jacks mounted onto the front panel of each module.
• Ability of power utility users to combine industrial protective relays with the Protective Relaying Training System to obtain equipment setups that correspond to existing one-line and three-line diagrams.
