Count on our Engineering Expertise to provide you with an effective Snubber Circuit Study

About Us

The Power Systems Engineering team at SnubberCircuitStudy.com can perform transient recovery voltage study and frequency response studies on transformers and associated system components using the Electromagnetic Transients Program (EMTP) and design methodologies to determine the transient response, and properly recommend transient mitigation equipment.

The switching transient study can be simulated in EMTP. The various transient concerns described above including primary switching of transformers, arc-furnace transformer switching, motor and generator switching, generator breaker transient recovery voltage (TRV) evaluation, capacitor isolated switching and back-to-back switching, switching of shunt reactors, series current limiting reactors and simulation of ferro-resonance and internal resonance.

Why Snubber circuits?

When a snubber is connected to a device of choice, it can absorb voltage spikes and normalize any abnormality or disturbance in the voltage waveform. They are most effective in mitigating fast-rising transient voltages and in attenuating reflections and resonances before they have a chance to build up. They are also employed to reduce the frequency of an electrical disturbance.
 

Advantages:

A snubber circuit can reduce over-voltages and high frequency disturbances due to the following, but is not limited to

doneA lightning strike
doneA circuit breaker interrupting a transmission line
doneSwitching in or switching out of lightly loaded transformers
doneFlashovers and restrikes after closing of circuit breakers
doneFaults in the system
doneLoss of generation and sudden changes in load
doneFerro-resonances
doneFerranti effect
doneSwitching of a heavily inductively loaded transformer for example in accelerating or stalled motors, arc furnace transformers and reactors
Snubbers are most useful for the protection of power transformers against high TRVs and abnormal frequencies.

Methodology

Snubbers usually consist of a capacitor connected in series with a resistor and both are connected in parallel with the desired connection point. 

Normal operating conditions

Under normal operating conditions, impedance of the capacitor is very high, effectively “isolating the resistor R from the system at normal power frequencies, and minimizing heat dissipation during normal operation.

High frequency transient conditions

Under high frequency transient conditions, the capacitor offers very low impedance, thus effectively “inserting” the resistor R in the power system as cable terminating resistor, thus minimizing reflection of the steep wave-fronts of the voltage transients and effectively dampening them.
