Description

GE IS200ECTBG1ABB

Technical Specifications

  • Board Type: Excitation Regulator/Control
  • Series Compatibility: GE Mark VI / Mark VIe
  • Output: PWM or analog firing signals for SCRs.

Functional Features

  • Precise automatic voltage regulation (AVR).
  • Reactive power (VAR) and power factor control.
  • Under-excitation and over-excitation limiting.

Application Scenarios
Installed in generator excitation panels at utility and industrial power plants.

Performance Parameters

  • Fast dynamic response to load changes.
  • High-resolution voltage sensing and regulation.

Material Composition
High-reliability PCB with precision analog components and protective encapsulation.

Structural Characteristics
Rack-mountable or plug-in module with multi-pin connectors for field and power wiring.

Working Principle
Compares generator terminal voltage to a reference setpoint and adjusts the firing angle of the exciter’s silicon-controlled rectifiers (SCRs) to maintain stable output.

Installation Requirements

  • Disconnect all exciter power before servicing.
  • Calibrate using manufacturer-approved test equipment after installation.

Usage Precautions

  • Never adjust calibration potentiometers without proper training.
  • Ensure cooling fans are operational to prevent thermal damage.
