Transients Caused by Glow Fluorescent Lighting
Environment:

Analysis:
Target: 1-phase 2-wire, 100V circuit
This is an example of measuring transient overvoltage when turning on glow fluorescent lighting.
A glow fluorescent light incorporates a glow
lamp and is widely recognized as a low-cost
alternative to fluorescent lighting.
A fluorescent light needs to be warmed-up for
its electrodes to be switched on. A glow lamp
is provided for this purpose. It flashes to
warm-up the electrodes before the fluorescent
light is actually turned on.
Transient overvoltage is generated at the first
flash of a glow lamp, which affects electronic
equipment located nearby.
