In today’s power systems, a large variety of substation equipment can be found. The characteristics of the equipment differ in function, design, technology and age. Aside from these characteristics, equipment maintenance depends on the application in the system and the philosophy being employed. Testing on the apparatus is usually performed by several testing teams throughout the equipment’s lifetime. In order to support the required workload, these teams need to be able to share all relevant asset data such as nameplate data and test results. PTM helps utilities master this challenge.

Distance relays identify the zone in which the fault occurs by measuring the impedance of the fault loop. Since the impedance of the ground differs from the impedance of the conductors, the relay must apply a correction factor to determine the distance of a ground fault from the relay. The necessary measurements to accurately determine the correct residual compensation factor (k-factor) are shown.

This video shows a test of a 220 kV circuit breaker, which has four interrupters per phase and independent mechanisms, making it rather complex to test. Nevertheless, the used test equipment allows testing it in one go.

After explaining the single components of the test system, the video shows in detail how to set it up. Then all common tests are performed without any rewiring, including motor current, timing tests, motion measurements, contact resistance test, dynamic contact resistance test, and minimum pickup test.

Energy transmission uses high voltage levels in order to transfer energy over long distances with minimum losses. In substations, the high voltage levels are transformed to medium and low voltage levels for distribution. The corresponding medium- and low-voltage power grids are highly interconnected, and thus require many circuit breakers in order to make or break any required connections.

However, the most important task of circuit breakers is probably breaking a fault current. Breaking high fault currents that are many times the rated current within a fraction of a second requires breakers to be in perfect condition. Thus, they must be regularly tested in order to make sure that they work when it really counts. Routine tests will typically include timing and contact resistance measurements. Additional tests allow a more comprehensive condition assessment of all breaker parts. These can include motor current, dynamic contact resistance, and contact travel. Test devices with an inbuilt power supply can even test breakers in undervoltage conditions and find the minimum voltages necessary for trip, close, and undervoltage coils. All of these tests combined reveal important information about the planning and execution of timely breaker maintenance. Condition-based maintenance can help preventing breaker malfunction, prolong breaker lifetime, and minimize unplanned outages; for a safe and reliable supply of electric power for everyone.

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.

Voltage-Based-Timing measurement, or VTM, indicates that the voltage of a medium voltage switchgear in service is used to detect the state of the main contacts.

The easiest way to do this is to use the Voltage Detection System, or VDS, of the switchgear.

In this video, Andreas Nenning, OMICRON product manager of the CIBANO 500, shows how this is done:

- how to connect to the VDS interface with the circuit breaker test set
- how to accurately measure the states of the main contacts
- how to record the voltages of the primary conductors
- and how to get the calculated operation times.

Zestaw do testowania wyłączników #OMICRON CIBANO 500 oferuje zaawansowane metody testowania wyłączników wysokiego i średniego napięcia. Urządzenie testowe może wykorzystywać swój wewnętrzny zasilacz, miernik czasu i miernik µOhm w celu wykonania szeregu testów wyłączników.

Rutynowe testy wyłączników zawierają pomiary czasu i rezystancji styków. Odciski palców poprzez dynamiczne pomiary rezystancji w połączeniu z pomiarami krzywych ruchu i prądu silnika, pozwalają na odkrycie trendów degradacji.

W idealnym przypadku, testy wyłączników powinny również obejmować testowanie wszelkich specjalnych funkcji wyłącznika, takich jak wykrywanie stanów przepięcia i podnapięcia, lub pomiar minimalnego napięcia niezbędnego do zadziałania i zamknięcia wyłącznika (test minimalnego odbioru).

CIBANO 500 pozwala użytkownikom na testowanie wszystkich tych funkcji za pomocą jednego urządzenia. Ten film pokazuje jak wyłączniki średniego napięcia mogą być kompleksowo testowane za pomocą CIBANO 500.
