Troubleshooting ESP Wire Failures

Common wire failures in discharge electrode systems can be a very serious problem with the potential to force the shutdown of a precipitator’s complete electrical field. Common causes of wire failures include:

• Warped plates that change the wire-to-plate distance
• Overvoltage
• Metal fatigue
• Chemical attack
• Mechanical failure
• Eroded wire frames
• Full hoppers
• Improper weight sizes
• Oscillation
• Swinging lower wire frames
• Corrosion
• Improper rapping
