The 0.2 kW Protective Relaying Training System is a complete program that extends training in protective relaying beyond the operation and calibrations of individual relays into broader circuit applications. The program provides hands-on training at the system level in Generator Protection, Transformer Protection, and Induction Motor Protection.

The 0.2 kW Protective Relaying Training System consists of several modules, which can be divided into five groups: Common Electrical Modules, Power System Modules (Series 3700), Protective Relaying Control Station, Protective Relays (Series 3800), and Additional and Optional Equipment. These modules are described in detail below:

Common Electrical Modules – Power supply, synchronous generator, induction motor, prime mover / dynamometer, resistive loads, voltmeters, ammeters, and others. Most of these modules are part of the 0.2 kW ElectroMechanical System (EMS), Model 8001 or 8006.

Power System Modules, Series 3700 – Modules specially designed for training in the protective relaying area, including current transformers, voltage transformers, power transformers, source impedances, a transmission grid, and others. These modules are designed to be installed in an EMS workstation.

Protective Relaying Control Station – A mobile rack for protective relay operation, including a dc power supply, dc control relays for system studies, and an interconnection panel to facilitate connection of the protective relays to the system to be protected.

Protective Relays, Series 3800 – Selection of protective relays. Each relay is mounted on a metal panel which facilitates relay installation in the Protective Relaying Control Station. Each relay panel is equipped with fault switches that allow fault insertion for troubleshooting at the system level. The following types of protective relays are available: undercurrent/overcurrent, undervoltage/overvoltage, synchronism check, underfrequency/over-frequency, phase balance, phase sequence, reverse power, and power factor.

Additional and Optional Equipment – Various modules, such as distribution busses, a ring bus, transmission lines, distribution transformers, protective relays, and reactive loads are available. These modules can be added to the basic 0.2 kW Protective Relaying Training System to allow the instructor to create more elaborate hands-on exercises.
