تابلوهای خازنی 62.5KVAR

تابلوهای خازنی 90KVAR

• اعتبار قیمتها تا پایان اسفند 1385 می باشد.
• برای تابلوهای خازنی با توان راکتیو بالاتر لطفاٌ تماس حاصل فرمائید.
• میزان تابلوهای خازنی مورد نیاز با اندازه گیری جریان تعیین می شود.
• برای برخی خطوط تولید خازنگذاری بصورت توزیع شده به صرفه تر از نظر فنی و اقتصادی است که با بازدید از خط شرایط مورد بررسی و تحلیل قرار خواهد گرفت.
• نصب تابلوهای خازنی در شبکه های برق بر اساس محاسبات می تواند به کاهش هزینه های برق مصرفی و بهبود دامنه ولتاژ و عملکرد ماشین-آلات گردد.

As a goal in power quality improvement solution we can say:

"Prevention is very very better and simpler and economical  than treatment "

 for example if we can use an inverter that its harmonics is acceptable , this way is economical and simpler than we use passive filters for harmonic mitigation and reduction.

We can classify PQ improvement solutions in three category:

1- without budget

like: changing position of capacitor banks , not starting big loads in same time , power network single line changing , …

this solutions need to having a good knowledge  and experience of power and conditions of load manner.

2- low budget

        like changing inverters and  control equipments, nonlinear loads reducing , …

3- high budget

like: passive filter installing , using active filters and active conditioners and stabilizers , ..

WHEN IS CONSULTING NECESSARY?
Consulting is typically necessary when your operations are being affected by: Equipment Shutdown, Hardware Failure, Software Programming Contamination, Programming Errors, Noise Interference, Control Problems, Component failure, Transformer and Conductor Overheating, Opening of Breakers/Blown Fuses, Power Supply Failures, Capacitor Bank Damage, Current in Grounding Conductors, Lightning Damage, Personal Shock.

OUR CONSULTING SERVICES INCLUDE:

• Review of source problems to discuss problem symptoms, effect on operations, period of problem, time problem occurs.
• Review of electrical plans to verify electrical mains, sub-mains and panels in accordance with site drawings.
• Equipment specifications verification to determine susceptibility and performance levels of equipment or loads being affected.
• Facilities visual inspection to observe any conditions requiring improvements.
• Measurements of voltage, current levels, power factor, harmonic distortion, voltage fluctuations, transients, etc.
• Earth ground testing to verify quality of grounding system.
• Electric service continuity testing to verify proper return path ground fault protection.
• Utility AC line inspection to observe current level of service and determine economical methods of improving overall site power.
• Inspect site lightning and surge suppression equipment for proper installation and grounding to ensure that lightning currents are dissipated into earth grounding system.
  
  

CONSULTING REPORT INCLUDES:

• Written Report with Findings, Measurements, Analysis, Recommendations and follow-up plan.
