Sentence examples for zero sequence from inspiring English sources

A systematic comparison with matrix approaches demonstrates that IEC 60909-2 formuladdsds the zero sequence self and the zero sequence mutual impedance between the two circuits.

Consequently, zero sequence mutual impedance between the two circuits cannot be neglected or mixed.

It is worth noting that the zero sequence mutual impedance between parallel circuits installed on the same tower may be as high as 50% (or more) of the zero sequence self impedance of a circuit alone.

In addition, the new technique helps mitigate the zero sequence current flowing through the neutral of transformers during unsymmetrical faults.

In these documents, the use of an indicator that includes the zero sequence component is not obligatory.

While the circuit to measure the positive sequence impedance and zero sequence impedance were separately built with Ansoft Simplorer.

Based on a complete set of onsite zero-sequence measurements taken in three power transformers, transformer zero-sequence performance is analyzed in relation to internal design features such as stabilizing winding position relative to high-voltage and low-voltage windings or the presence of magnetic shunts in the tank.

It complements a previous companion paper that presented experimental zero-sequence measurements and equivalent circuit calculations for three power transformers.

It is based on the measurement of the zero-sequence voltage and zero-sequence current.

In this paper, the fifth harmonic of zero-sequence current, line's power and energy of the zero-sequence current are used as the fault feature.

Then a composite compensated voltage is formed based on the zero-sequence voltage and zero-sequence current to evaluate a revising factor for every feeder respectively.
