Industrial Electrical Testing: Power Factor Test Sets | Tan Delta

Power factor and tan delta testing, the process of measuring capacitance and dissipation, helps you determine the condition of a system’s insulation in bushings or between windings. As time wears on, insulation of a system will begin to degrade, or impurities like dirt and moisture may start to compromise it. This will create a conductive path to the current, consequently leaking electric current flowing through the system and reducing capacitance. Ideally, the aim is to keep the ratio of resistive component to capacitive component of an insulator low. This ratio is known as tan delta, or dissipation factor (power factor).

Advanced Test Equipment Rentals stocks equipment that can measure power factor and tan delta of your system. You can determine capacitance and dissipation at varying frequencies and identify any age degradation or impurities sooner, before the damage becomes irreparable. Advanced Test Equipment Rentals carries power factor and tan delta test equipment from top manufacturers like Tettex, Megger, OMICRON, Doble, and more. Power factor and tan delta test equipment can be applied to power transformers, instrument transformers, bushings, capacitors, circuit breakers, and surge arrestors.
