OSKAR® is the new benchmark in respekt of dynamic voltage control -
dynamic power supply voltage controller
OSKAR® setting new standards in power quality.
Voltage dips in the electrical power supply are one of the main reasons for expensive unscheduled production outages. The voltage range of +-10 % of the nominal voltage defined in EN 50160 has to be guaranteed by the utility only in 95 % of the 10 minute average values. Incidents which are shorter than 10 minutes cannot be avoided and may not be criticized.
IEC 61000 2-8 describes the impacts of voltage dips. If the remaining voltage is less than 85 % of the nominal voltage, typically problems with frequency converters and switch-mode power supplies will occur. According to own investigations commercially available contactors are in an undefined status if the voltage goes down to 80% of nominal voltage, even if the voltage dip lasts only for one period (20 ms). Also rugged consumers like asynchronous motors will be affected if the voltage drops to less than 75 % of the nominal voltage for several periods.
OSKAR® keeps the grid voltage highly dynamic at the desired target value and the load will ride through typical voltage dips without even taking notice. Typical voltage dips will be passed through brilliantly.
