“…and customer, respectively. The accuracy of the calculated network and customer currents can be proven with the condition of being equal to each other of the result of Equation (19) (19) In order to realize the contribution of the network and customer voltages to the voltage of PCC in what rate Equation (20) (21) …”

“…Many methods have been applied in order to keep the harmonic distributions within certain limits between the client and distribution network. Since the measurements taken from different points in a network at the same time is quite difficult and expensive [14]- [18], to be able to perform the measurements at the PCC more practical approaches should be developed [19]. Despite using various measurement methods in the determination of the total harmonic distribution at the PCC, none of them is practical.…”

In recent years, sinusoidal waveform of the current and voltage disturbs in the electrical distribution system because of the due to the increasing number of non-linear loads. Many standards of IEC and IEEE standards have been published in order to limit the voltage and current waveform distortion. The operators of the electricity distribution network widely use the power quality monitoring systems at the point of common connection (PCC). It has been identified that there are substantial number of harmonic currents excess of the standards transferred to the grid according to the data obtained from power quality monitoring systems. In case of exceeding the limits specified in the standards, there is a need to determine the network and customer responsibilities for the implementation of required sanctions. In this study, using recorded data at the PCC of a medium voltage electrical distribution system, voltage and current harmonic distortion responsibilities of the network and customer are determined by the improved harmonic current vector method. Up-to-date load model based on field measurement which provides more accurate results has been used instead of the constant load impedance in the proposed method.

“…The maximum slew rate, and zero sequence voltage are mentioned as potential single event indices. The Canadian electrical association uses two approved quality indices: RMS Overvoltage (RMSO) and Undervoltage (RMSU) (Bergeron,R., 1998). The indices are assessed over intervals equal to the time needed for equipment to reach its steady-state temperature.…”

“…Voltage Sag is defined as a short reduction in voltage magnitude for a duration of time. The characterization of voltage sags in terms of duration and magnitude vary according to the authority (Bergeron, 1998;Bollen & Styvaktakis, 2000;Sabin, 2000;Thallam, 2000;Thallam & Heydt, 2000). The IEEE STD 1159-1995 defines voltage sag as a decrease of RMS voltage from 0.1 to 0.9 p.u, for a duration of 0.5 cycle to 1 minute.…”

A proposed voltage sag index based on power flow equations is developed and investigated in this paper. The index supervises the power quality of a system, through calculating the voltage sag profile caused by an increase in reactive demand due to induction motor starting. Mathematical equations representing the load angle of the system are also derived. The accuracy of the index is investigated for a range of load, transmission, and distribution line X/R ratio values as well as various motor loading levels. Results demonstrate the effectiveness and applicability of the proposed index.
