The prime function of OptiV MAX II dynamic voltage restorer (DVR) is to reduce the voltage sags on power lines that supply power to sensitive equipments. The DVR is principally accountable for restoring the quality of voltage supplied to the end-user in case the voltage from the supply is not suitable to be used for sensitive devices. DVR allow consumers to isolate and protect devices from disturbances developed by sags and swells on the distribution network or power lines. Additionally, DVRs can also be used to address the trouble of harmonics generated by non-linear load in manufacturing machinery setup.

GridStone OptiV HV system provides a combined solution with super low-loss amorphous core HV/LV transformer with integrated variable voltage optimisation technology. GridStone OptiV HV is ideal for sites with the following profile:

High capability for surge current. Output frequency accuracy: < 0.1%. Wide frequency range. High Output voltage accuracy +/-1% or higher. IGBT control, Ultra fast response and correction time:High PF. Output with Isolating transformer .

Voltage optimization aims to reduce electricity usage, power demand and cost, improve the performance and working effiency of the loads by reducing supply voltage received. It can improve power quality by reducing harmonic and transient voltages as well as balancing phase voltages. A reduction and balancing in electricity supply voltage achieves a saving in energy consumption (kWh) and a reduction in maximum demand (KW & KVA). Voltage Optimization is not the same as Power Factor Correction.

The electricity usually travel very long distance from the generating plants to the customers. To ensure all customers get acceptable voltage levels considering the voltage drop and loading on the grid net work, the grid networks typically supply electricity voltage at high end of the range which is higher than required by most equipment to work at best efficiency. This can result in over voltage issues such as overheating and malfunctions, as well as increased energy usage and costs. For example Australia, statutory supply range is 230V, +10% to -6%, a range of between 253V and 216V. Averagely 247V is provided in many Australian facilities.

Galvanic isolation between the stabilizer and the main power supply. Change the voltage grade. Improve the balance of the phase voltage and provide a steady neutral point. Protection from voltage surge and cancel the triplen harmonics.
