ISUVOC Controller

The univeral controller for active filters, voltage supply and electronic power supply for high voltage test equipement.

General features of the ISUVOC-Controller:
• Usage of fiber optics between Controller and power electronics for immunity to HF-distortion
• Easy Commissioning with IPC-Panel
• Remote Control and Analysis via Internet possible (LAN)
• All Protections integrated (Hard- und Software)

Since 2008 the controller is used worldwide in various applications:

As an Active filter the ISUVOC-Controller operates together with fast LV-IGBT Technology. The ISUVOC-Controller has all necessary interfaces and acts together with power electronics in a closed loop control circuit to achieve the desired compensation values:
• Depending on the dimensioning of the power unit the power factor 1.0 can be hold at any load.

• It can compensate harmonics on low voltage side as well as on medium voltage level.
• Fast Reactive Power Compensation on Medium Voltage Grid (Pcc) up to 5 MVar
• Free programmable harmonic order and reactive power settings.
• Automatic Adaption to the grid impedance
• Transient-Recording of all events

• Fast Flicker compensation and load balancing
• Fulfilling all important standards as IEEE519, GB5/4, D-A-CH-CZ 301/04, EN50160 etc.
• Compensation of interharmonics and programmable band width possible

The ISUVOC Controller can also be used as Combination of Power Supply Drives and Active Filtering.

As Voltage- and/or Current AC-Source the ISUVOC-Controller can inject current harmonics to test  special transformers which are loaded by harmonics.
• As voltage-, current and/or frequency source  the controller can fullfill all IEC-measurement for any transformer type.
• Suitable for Partial Discharge Measurements
