خلفية

Henrad is a Belgian radiator manufacturer in the Caradan Group. و 55000 square meter factory in Herentals, Belgium consists of six production lines that totally can produce about 5000 علبة التروس يوميا. The production process are presses, لحام التماس لحام البقعة و, the nature of the process is very energy demanding and therefore puts great demands on the power grid. This together created large voltage drops in the feeding substation with the result of to high Pst values which would lead to flashing lights when Eandis, the local utility company, would connect other consumers to the same transformer.

طالبت شركة المرافق المحلية ان توقيت المحيط الهادي 95% value must not exceed 0,7. قياس القيم خلال 2009 provided by the well-known Belgian consultancy firm Laborelec showed tops in the Pst equivalent to 1,6. The task was very challenging since it’s a rapidly fluctuating load and also the many different load patterns that could occur since its very high number of welding machines.

Key benefits | Welding – بصيص:

  • Pst reduced from 1.6 إلى 0.63
  • Only solution with desired flicker mitigation performance without integration with welding lineseasier to instal
  • Fully autonomous solutionwill work with future production line upgrades
  • Integrated with existing passive compensation system

Solution –
the ADF P300 Active Filter system

Henrad chose to invest in the ADF P300 Active Filter نظام, a well proven solution. The market leading response time was a necessity for the customer to reach the values that the utility company demanded.

نتيجة, after installing the ADF Active Harmonic Filters

After installing the ADF Active Harmonic Filters Henrad has managed to keep their Pst value below 0,63 regardless of how many welding lines that are running. The reference values has been measured by Laborelec and approved by Eandis. كأثر جانبي من قيمة ميض خفضت Henrad has also seen stabilized production environment.
