HIGH VOLTAGE PROJECTS
SDC Industries have the in-house capability to design, manufacture and install the equipment you need – safely, on-time and on budget.
VARCAP & VARMATIC HV
The SDC Industries Varcap & Varmatic HV is a comprehensive range of low loss, environmentally friendly power capacitors with voltage ranges from 660V – 33KV
Capacitors can be supplied as loose units or finished assemblies. The individual capacitors can be utilised to replace existing capacitors. The complete assemblies can be supplied as fixed or automatic banks which incorporate Vacuum/SF6 contactors. A design service is available for individual customer requirements/harmonic filter banks.
The Varmatic HV assembly offers the latest technology in the supply of automatic capacitive reactive power combining very high quality components with state of the art engineering expertise
VARCAP HV
- All film dielectric, no PCB presence.
- Losses less than 0.2W/KVAr.
- Ratings 25KVAr – 400KVAr, single and 3 phase.
- Stainless steel welded container.
- Porcelain bushings. VARMATIC HV
- Designed to specific site requirements.
- Individual automatic stage sizes 50KVAr – 1000KVAr.
- Assemblies in free standing sheet steel enclosure complete with all control power supplies, HRC fuse protection, etc.
POWER SYSTEMS ANALYSIS
The SDC Industries VR process begins with a POWER SYSTEMS ANALYSIS of your electrical system. From the outcome of this report, our highly trained in-house engineers can design a unit to suit each client’s specific requirements.
POWER QUALITY FOR THE OIL INDUSTRY
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.
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
VARMATIC RAPIDE BENEFITS:
IMPROVES POWER QUALITY
ABSORBS HARMONIC CURRENTS AND THEREFORE REDUCES TOTAL HARMONIC DISTORTION
ALLEVIATES STRESS ON CABLES, SWITCHBOARDS, TRANSFORMERS AND GENERATORS
THE MICRO-PROCESSOR CONTROLLING THE UNIT ENSURES TRANSIENT-FREE SWITCHING
PREVENTS VOLTAGE DROPS AND FLICKERS TYPICALLY OCCURRING IN REAL-TIME APPLICATIONS
MORE CONSTANT ELECTRICAL LOAD
REDUCED OPERATIONAL HOURS OF GENERATORS, THEREFORE REDUCING MAINTENANCE COSTS
