The SDC Industries VARMATIC RAPIDE (VR) is an industry-leading solution manufactured to improve power quality on oil and drilling rigs.

This innovative, all-in-one unit’s internal components and software package provide software intelligence to counteract the effects of :

  • Power Factor

  • Harmonics

  • Voltage Sags

  • Voltage Swells

  • Voltage Flicker

  • Transients

“Power Quality” is a term used to define any occurrence of voltage, current or frequency deviation on your low voltage power system that results in equipment failure, process interruptions and power system inefficiency.

Switching of reactive loads allows harmful transients, harmonics and other problems to make their way through the power system. By utilising the VR, these problems can be minimised or eliminated. In addition, the VR would be beneficial when reactive compensation is required to meet specific load demand.

The unit is capable of :

  • Switching at intervals down to 1 cycle to counteract the effect of peak loads

  • Removing all transients from switching

  • Reducing drops in voltage and any resultant flicker

  • Maintaining a long life-span, due to its robust nature

Varmatic Rapide

The SDC Industries is capable of switching large amounts of reactive compensation in and out of circuit in times down to 1

Each system is manufactured to client specification, following on-site measurements taken using sophisticated power monitoring equipment. It can be installed on systems up to 690V; 50/60Hz; single or 3 phase. The system is protected by high speed fuses and contains built in harmonic filtration. Each unit comes with high power thyristors and a three phase analyser included. All capacitors and reactors used within the system are designed and manufactured to a high specification in our premises in East Kilbride.
