Oxygen — voltage sag compensator
Country: United Kingdom · Model: Oxygen
Oxygen is a voltage sag compensator based on double conversion that corrects the voltage in less than 1 cycle. It covers sags of up to 50 % for up to 1 min and holds a continuous range of ±20 % at 0,5 % accuracy. Typical loads are frequency converters, medical and semiconductor equipment.

Description
This intelligent compensator is meant for sensitive loads where even a brief sag in the supply means a stopped process. Examples are frequency converters, medical equipment and semiconductor equipment. It is built on double conversion, and the correction time is shorter than 1 cycle of the mains, so the equipment has no time to react to the sag. Compensation lasts for up to 1 min, so longer sags call for another means of protection. In continuous operation the unit holds ±20 % at 0,5 % accuracy and also acts as a stabiliser for slow deviations.
How to choose
First compare the depth and duration of sags on your network with the figures of 50 % and 1 min. If the deviations are slow and long, the electromechanical Light Industrial (EMS 2100) rated 44–100 kVA with 0,5 % accuracy is the better fit. Oxygen is chosen when short sags are the main problem and the continuous range of ±20 % is sufficient.

FAQ
How fast does the compensator correct a voltage sag?
The correction time is shorter than 1 cycle of the mains. The technology is double conversion.
Which voltage sags does Oxygen compensate?
Sags of up to 50 % lasting up to 1 min. Longer sags need other protection.
What range and accuracy does it give in continuous operation?
The continuous range is ±20 % at 0,5 % accuracy.
Which loads does the compensator protect?
Sensitive loads such as frequency converters, medical equipment and semiconductor equipment.
How does it differ from an electromechanical stabiliser?
Here the principle is double conversion with correction in less than 1 cycle. In Light Industrial (EMS 2100) regulation is done by Rotavolt autotransformers with 0,5 % accuracy.
