The wider use of equipment with non linear absorption such as rectifiers, speed variators, drives, switching power supplies, has caused, besides traditional and well known voltage fluctuations, the spreading of a new insidious type of electrical fault: harmonic distortion.
Companies producing electric energy generate the correct voltage. However, failures on the line, atmospheric conditions, continual load variations and disturbances generated by the actual users make it impossible to guarantee every user a steady voltage within the tolerance bandwidth stipulated in the supply contract.
'GEESYS' series of electrodynamic voltage stabilizers offer a reliable and tested economic solution to inconveniences caused by voltage fluctuation. To use GEESYS SCVR is a real investment because the elimination of the inconveniences means a reduction in costs and an increase in productivity. Very often it is only necessary to avoid a few minutes machine downtime or just one failure to repay the cost of the stabilizers. GEESYS SCVRs are particularly suitable for applications that require:

• High reliability
• Capability to compensate wide mains voltage variations
• High precision of stabilized voltage
• Stabilizing of high power services
• Simple and limited maintenance
• Networking

Unique Features GEESYS has developed state of art DSPIC based controller to stabilize utility voltage. Apart from its standard feature it has following unique features to improve reliability, serviceability and reduce system down time.

• Energy meter with RTC (Optional)
  Provides accurate Energy Consumption (Kwh) data with Real Time Clock. Also provides useful data like KVA, KW and Power factor. Compatible with GEESYS servo-control cards and so that all the energy related data can be seen on the same display where servo-voltage stabilizer data are being displayed.
• Variac protection
  Utility voltage levels are very dynamic and change over time is unpredictable. Higher voltage can generate catastrophic failure in SCVR (mainly Variac) which impacts on higher down time . This feature isolates the VARIAC whenever voltage goes high at cutoff limit and restores the same once utility voltage comes back to normal range.
• Carbon brush failure protection
  Carbon brush failure is frequent phenomena due to wear and tear. This failure results in higher down time or uncontrolled voltage to machines. GEESYS has developed algorithm to detect carbon brush loss. This feature helps user to take preventive action to reduce down time and MTTR.
• Sensor less voltage feedback
  Sensor less control reduces probability of sensing transformer failure and increase system reliability. GEESYS DSPIC based controller does not use any sensing transformer to sense the input and output voltage. Faster feedback and sensing due to software filter and algorithm inside DSPIC increases system response.
• Real Time Clock (RTC)
  Helps to log event occurrence (e.g. over voltage, under voltage, over load) along with date & time, which can be viewed later on. This information along with equipment down time / up time can be helpful to analyze various data like, down time for maintenance, production rate, and fault analysis
