To conduct current analysis using an electrical discharge detector, an average of the electrical flux generated around the motor casing is taken in 30-second intervals. Once a value is acquired, a determination can be made as to whether the electric current passing through the bearing is causing the defect.

A corona discharge is an electrical discharge caused by the ionization of a fluid such as air surrounding a conductor carrying a high voltage. It represents a local region where the air (or other fluid) has undergone electrical breakdown and become conductive, allowing charge to continuously leak off the conductor into the air. A corona occurs at locations where the …

Applications. The properties and effects of electric discharges are useful over a wide range of magnitudes. Tiny pulses of current are used to detect ionizing radiation in a Geiger–Müller tube.A low steady current can be used to illustrate the spectrum of gases in a gas-filled tube.A neon lamp is an example of a gas-discharge lamp, useful both for illumination and as a voltage regulator.

Electrical discharge machining (EDM) is a process of removing material by exposing it to repetitive controlled electrical discharges. It is suitable for thermoelectric phenomena. When a discharge occurs between the electrode/wire and the workpiece, heat energy is generated on the workpiece. This leads to the removal of the material layer.

Electric discharges can convey substantial energy to the electrodes at the ends of the discharge. A spark gap is used in internal combustion engines to ignite the fuel/air mixture on every power stroke. Spark gaps are also used to switch heavy currents in a Marx generator and to protect electrical apparatus.

The challenge with VFDs is the potentially damaging electrical current that is caused by a buildup of voltage along the rotating motor shaft. As the voltage accumulates on the shaft, it seeks the path of least resistance to the ground, which typically is the bearing or seal closest to the shaft. One of the first "symptoms" of bearing ...
