Power system transients are voltage or current spikes, sudden and brief increases or decreases in the supplied power. These can be harmful for some types of electronic devices, and can be seen by a brief flicker of either dimmer or brighter light from light bulbs.

Does capacitor banks produce harmonics?
No, capacitor banks reduce harmonics. They act like a low pass filter. They also raise voltage by compensating for inductance and bringing the power factor back closer to 1. Capacitor banks in the power system can cause transients when randomly closed - many utilities use zero voltage closing equipment, or inductors to counteract this short time harmonic problem.
What is subtransient current?
Transients -- they can be currents or voltages -- occur momentarily and fleetingly in response to a stimulus or change in the equilibrium of a circuit. Transients frequently occur when power is applied to or removed from a circuit, because of expanding or collapsing magnetic fields in inductors or the charging or discharging of capacitors.
What happens if reactive power enters the system?
Reactive power entering the system will increase the system voltage.

What are the effects of Electrical Transients Analysis services?
When transient voltages are present, motors will run at greater temperatures. Shocks can create "micro-jogging" by altering the motor's normal timing. Motor vibration, noise, and excessive heat are all symptoms of this type of disruption. The insulation in motor windings deteriorates with time and eventually fails. Transients affect the operation and performance of several components of the power system, as well as loads, measuring and protective devices. The nature and length of _power system transients are linked to circuit breaker operation and overvoltage caused by high voltage line switching. The system's insulations are broken by large voltage transients. Current transients of a large size can burn out equipment and instruments. Transients can cause relays to malfunction and circuit breakers to trigger incorrectly. The magnetic characteristics of core materials used in electric machines may be altered by a large number of direct or indirectly produced oscillatory transients.
