Refurbished Circuit Boards

ProTec offers its customers a circuit board refurbishment and exchange program designed to extend the operational lifetime of analog voltage regulators still in service in the power generation industries.

ProTec’s exchange program provides reliable circuit board upgrades for a variety of analog excitation systems, including Alterrex and WTA. As electrical equipment ages, performance can be challenged by the failure of older circuit boards. To counter the effect of aging components, ProTec replaces all:

  • Semiconductors
  • Capacitors
  • Potentiometers
  • Instrumentation and Controls
  • Power Resistors

In addition, ProTec checks all 1/2 watt resistors in good condition for the correct resistance value, but not replaced unless specifically requested by the client. A defective solder joint on a circuit board could lead to major failure under stress and render equipment out of commission. With this in mind, all solder joints on circuit boards are checked and reflowed or replaced if necessary. Please note that in the event a circuit board needs an immediate return, ProTec has an exchange program for GE Alterrex and some Westinghouse WTA boards.

Our circuit board exchange program provides customers with immediate turn around, resulting in a swift refurbishment without major delays. The value of using a refurbished circuit board from ProTec over a repaired circuit board ensures that you receive OEM-quality components that are cost-effective in comparison to replacing circuit boards with a costlier new board. ProTec is in the business of taking care of its customers and extending the technical life of their equipment.

ProTec’s circuit board refurbishment service includes a burn-in period of 100 hours to ensure the reliability of its components and identify any potential flaws—resulting in exceptional quality and performance for your peace of mind. Refurbished circuit boards from ProTec are also calibrated in their existing voltage regulator cabinet, whenever available. Alternatively, ProTec stocks replacement parts—including voltage regulator cabinets from diverse manufacturers—that are readily available for use during refurbishment.
