Why Do Capacitors Fail?
Q: Why are there so many infant capacitor failures?
A:
Q: What causes capacitor degradation?
A:
Q: What are the signs of a failing capacitor?
A:
Q: Why should a capacitor be replaced?
A:
Q: After how much deterioration should a capacitor be replaced?
A:
1. Substandard materials
2. Poor capacitor design
3. Improper & inadequate process control
1. Excessive temperatures to the capacitor designs
2. Voltages excessive to the design of the capacitor
1. Loss of capacitance
2. Increase in dissipation factor (similar to ESR)
PSC Motors are designed to run at an optimal load point. This optimal
load point is determined by utilizing a specific run capacitor value
(mf). Degradation in capacitance translates into deteriorated motor
performance and less than optimal system performance.
Deteriorated motor performance can cause the following:
• Temperature rise
• Bearing wear
• Insulation breakdown
• Increased noise
• Increased energy consumption
• Improper cycling
• Stress on other components
Most OEM’s mandate a tolerance of 6% on capacitance. For a reference
table on Capacitor Ratings and Meter variation, please see table 2 on
page 15.
