Rotating machines, such as generators and motors, are highly important assets in power generation and industrial applications. Machine reliability and availability are crucial to ensure a reliable power supply. Premature failure may lead to significant economic losses, due to unexpected outages and possible damage to the asset itself.

To plan maintenance effectively, it is essential to have accurate condition information about when components need repairing or replacing.

A variety of off-line and on-line diagnostic methods conducted during commissioning and acceptance testing as well as in-service maintenance on rotating machines allow a reliable insulation condition assessment.

For all of these diagnostic methods, we offer you the matching testing and monitoring solution. With these solutions, you can perform a fast and accurate condition assessment on a variety of electrical machines to identify potential problems and risks quickly.

Circuit breakers perform three main tasks: When closed, they must conduct the current as effectively as possible. When open, they must insulate the contacts from one another as effectively as possible. In the event of a malfunction, they must disconnect the fault current as quickly and reliably as possible, thereby protecting all subsequent equipment. In the US market and regions of frequent earthquakes, the most popular high-voltage circuit breakers are "dead tank" units, whereas in central Europe "live tank" breakers are standard. In other parts of the world, both circuit breaker types can be found.

In the worst case, a circuit breaker might stand still for several years, but then, in the event of a malfunction, it has to disconnect fault currents of many kiloamps reliably within just a few milliseconds. Typical faults that occur on circuit breakers are short circuits in the coils, incorrect behavior, for example due to worn contacts, as well as damage/wear to the mechanical connections or the insulation material. Therefore, circuit breakers need to be regularly and carefully tested.

Circuit breaker testing typically focuses on performing motion and time measurements on the units. However, our testing solutions have revolutionized circuit breaker testing. The testing solutions we offer include systems that can supply power during the testing process and are capable of measuring the micro-ohm resistance across the closed contacts. Performing the tests without use of the station battery greatly increases safety throughout the testing process.
