What are the transients or over voltage spikes?
It's a condition of high and fast voltage rise in one or more phases.
Upload time: 10 nano-seconds a 100 micro-seconds.
Duration: 0,5 micro-seconds a 2000 micro-seconds.
Amplitude: 50 volts to a peak de 20000 (+) volts.
What are the causes that generate transients or over voltage spikes?
The 80% Internal Causes.
Capacitor Bank Switching.
Heating Resistors Switching.
Non-linear Loads Switching VDS, UPS.
The 20% External Causes.
Damage to subestations.
Accidents in Towers, Insulators, Conductors.
3D Effect of transients or over voltage spikes.
Destruction (Catastrophic Failures)
Degradation (Premature Aging)
Deprogramming (Catastrophic Failures)
