The power factor measurement has long been accepted as an invaluable tool for identifying insulation defects, such as ageing, deterioration, moisture ingress and localized failures, involving the ...

The instrument works on the principle of a combined bridge-vector-meter and it is capable of analyzing capacitive and inductive loads. HAEFELY HIPOTRONICS has launched the new high precision tan δ/ ...

The scope of this article is to introduce a method to measure the power factor in a 50 Hz alternating current transient. The circuit shall be a R-L type. By acquiring only the current wave and, ...

When it comes to the most typical cause of poor power factor in a facility, motor inductance is a likely culprit. The problem worsens when motors are not loaded to their full capacity. Harmonic ...

Measurement of standby power is important to the engineer designing, testing and certifying power supplies and everyday domestic and office appliances. While the amount of power used per device is low ...

We all know that electric utilities in the United States generate electricity at various 60-Hz voltage levels that result in a sine wave waveform. The height, or amplitude, of this sine wave is called ...

Advanced power-line monitoring systems combine power-supply monitoring, load-balancing, protection, and metering functions. This allows the power utilities to efficiently deliver grid power while ...

Accurate modeling of power electronic converters, i.e., obtaining control to output transfer function, must include series resistance of capacitors and inductors. A simple method allows measurement of ...
