Professional Calibrators

A powerful test system designed for primary injection testing of protective relay equipment and circuit breakers. It is also used to test the transformation ratio of current transformers and for other applications that require high variable currents. Up to 8 kA can be generated. The ODEN™ A system consists of a control unit together with one or two current units. All parts are portable, and ODEN A can be quickly assembled and connected.

The SVERKER 760 features many functions that make relay testing more efficient. To cite one example, its powerful measurement section can display (in addition to time, voltage and current) Z, R, X, S, P, Q, phase angle and cos ϕ. The voltmeter can also be used as a 2nd ammeter (when testing differential relays for example). All values are presented on a single easy-to-read display. Thanks to its built-in variable voltage source (amplitude and phase angle), SVERKER 760 can also test directional protective equipment efficiently. Automatic reclosing devices can also be tested – just as easily. Fine regulation of current is easy thanks to the built-in set of resistors.

Acoustic Calibration is available on all types and brands of instrument with our comprehensive Calibration Service based in Newcastle upon Tyne.
Sound Level Meters are classified by two different types (Class/Type 1 and Class/Type 2) and can often be known as Noise Meters or Noise Dosimeters. The different classes refer to the accuracy level of the results given by the meter with Class 1 being the more accurate of the two options.

For example, the use of Sound Level Meters is widespread across industry with the importance of issues such as Noise at Work Regulations, Building Acoustics and other forms of Environmental Monitoring being just some of the key reasons. Regular calibration of Sound Measuring Equipment is therefore essential in industry so users can be certain results being provided by the meters conform to the relevant British Standard BS EN 61672-3:2013.
