Transformers are important and expensive assets in the electrical power grid. Therefore, it is crucial to protect them from damage due to overload and short circuit.

The most common type of transformer protection is differential protection. The principle behind differential protection is Kirchhoff's nodal law. It states that the algebraic sum of currents at a node must be zero. This law can be used to formulate a condition that detects a fault in the protected area.

We apply the differential protection principle not only to transformers, but also to rotating machines, busbars and lines as well.
Modern protective relays use complex algorithms and adapt to network and failures. Simple function tests are often no longer sufficient for testing such relays. Our unique software RelaySimTest covers these new demands with a transient simulation of the primary power system.

In this episode, Martin Pfanner, OMICRON product manager for Primary Test Manager software, discusses what contributes to making electrical testing on primary assets faster, easier and safer.

One important aspect of testing efficiency is having a single, automated software platform that provides users with guided workflows as well as central data management and reporting for all recommended tests on electrical assets. One such platform is OMICRON’s Primary Test Manager software.

The intermediate infeed effect is a phenomenon that occurs in multi-terminal distance protection schemes. For example, the additional current by a third terminal will rise the voltage at the intermediate busbar – this leads to an incorrectly calculated impedance within the protective relay.

The impedance increases and thus the distance protection could detect the fault location too far away and trip in a wrong zone. The protection system will not function as desired and will violate requirements for speed and selectivity. Therefore, it is important for protection engineers to know the effect and handle it correctly.

Modern protective relays use complex algorithms and adapt to network and failures. Simple function tests are often no longer sufficient for testing such relays. Our unique software RelaySimTest covers these new demands with a transient simulation of the primary power system. It can reveal failures created during calculations as well as during setup of the relay or a protection scheme, requiring only a minimum of test steps.

The #OMICRON CIBANO 500 circuit breaker test set offers advanced testing methods for high and medium voltage circuit breakers. The test device can make use of its internal power supply, timing meter and µOhm meter in order to perform a number of tests on circuit breakers.

Routine tests on circuit breakers will typically include timing and contact resistance measurements. Fingerprinting through dynamic resistance measurements combined with measuring motion and motor current curves, allow deterioration trends to be discovered.

Ideally, circuit breaker tests should also include the testing of any special functions of a circuit breaker, such as the detection of overvoltage and undervoltage conditions, or the measurement of the minimum voltage necessary to trip and close the breaker (Minimum pick-up test).

CIBANO 500 allows users to test all of these functions with a single device. This video shows how medium voltage circuit breakers can comprehensively be tested with CIBANO 500.
