DN-V Series Voltage Stabilizing Harmonic Filter

One,Product Overview

Currently, voltage sag is prevalent among various electrical power quality issues.Or too highA frequently occurring, severely harmful power quality issue.Based on the power systemStatistics indicate that voltage dropsOr overvoltageUser complaints accounted for80% plus, due to harmonics and switching operationsThe lowVoltageOr high voltageConsumer complaints regarding power quality issues are not reaching us. 20%。

Common voltage sagOver-voltageThe reasons are as follows:FiveSpecies:

1) Fault current-induced voltage sag：During a short-circuit fault in the transmission or distribution network, current sharply increases, causing voltage drops at the common voltage connection points. Simultaneously, these voltage drops propagate through the power grid, disrupting a large number of users.

2) Voltage sag caused by inductive motor start-up：When the induction motor starts under full voltage, the voltage value it needs to draw from the system is the same as when it's running at full load.5-10 times, this high current flowing through the system impedance will cause voltage sag.

3) Voltage dip due to lightning and lightning strikes，Lightning-induced flashovers of insulators and ground discharges in the lines are the primary causes of voltage dips in the system. During the rainy season or in regions prone to thunderstorms, equipment exposed to the open air is easily disrupted by lightning interference.

4）Voltage fluctuations caused by low or high power factor.No performance.PowerIn the systemCan cause line failuresThe voltageWastageThis isCapacitiveNo effectIncreasePower supplyVoltage:Reason。

5）Unpredictable偶然incidents: construction roadwork, traffic accidents, human errors, etc.
