Protective relays, energy meters, measurement transducers, and power quality devices are vital components of power systems. Regular testing of all these devices is necessary to ensure their reliability. OMICRON entered this industry in 1990 with the CMC, and quickly rose to its leading position through continuous innovation. And now, more than 10,000 CMCs are being used in more than 130 countries.

In some applications, current transformers with secondary taps are commonly used. Each tap represents a different number of turns of the winding and therefore a different current transformer ratio. The CT Analyzer Switchbox, a special accessory for CT Analyzer, can be connected to the taps of a multi-ratio current transformer. All tap combinations can then be tested in one test run, automatically and efficiently.

Operators have to deal with devices of all generations and specifications. Some relays still in use are electromechanical and operate on a 5 A nominal current, although a growing portion is made up of IEDs. Testing all these relays with a single test device requires a lot of power, high current amplitudes, a DC voltage source to supply the relay and, increasingly, IEC 61850 testing capabilities. This combination of requirements creates the need for a small, powerful and light-weight test device: the CMC 353.

Power plants and substations are the major components of the energy system. Aside from power transformers, the main parts of such a plant include instrument transformers, the protection and control system, as well as switching elements like circuit breakers and disconnectors. For a reliable supply of electricity, the correct operation of all individual components and their seamless interaction has to be assured - during the entire lifecycle of the plant.

Voltage transformers are used around the clock throughout the energy grid, and their life span can reach up to 40 years. During that time, the effects of aging, regular operation, network faults, or external influences may affect the integrity of a voltage transformer. Utilities perform various tests during commissioning and maintenance to find any irregularities that have been caused by transportation, installation or daily operation.

Metering current transformers have to accurately transfer system currents to electricity meters. Considering it is in operation 7 days a week, incorrect billing due to an inaccuracy of just one current transformer circuit in a single feeder may lead to significant financial consequences. Therefore, international standards define the accuracy requirements for metering current transformers.

CT Analyzer comprehensively measures all the essential parameters of metering current transformers within a minute. Its low weight of only 8 kilograms or 17 pounds makes using it on-site just as easy and convenient as in laboratories and test fields.

Important parameters of a protection current transformer are its ratio, its excitation curve, the knee point, its winding resistance, and the burden. CT Analyzer determines all relevant current transformer data during a test duration of approximately one minute: it measures the burden of the secondary circuit, the winding resistance and the excitation curve, calculates the accuracy limiting factor for rated and actual burden, determines its ratio, amplitude and phase angle accuracy, and verifies the polarity.

During commissioning, several tests on current and voltage transformers need to be performed to identify manufacturing errors or transportation damages, to verify correct installation and wiring and to measure the secondary burden. If problems occur during the operation of the plant, further tests will be performed to identify the cause of the error. With the CPC 100, many of these electrical tests can be performed on current transformers and voltage transformers with one single device, saving test time and labor costs.

Tests of distance relay teleprotection schemes should check both relays simultaneously, including their communication link.
This video shows a real test of a 110 kV overhead line. The protection was only out of service for one hour. The whole test could be conducted so efficiently, because it had been performed with OMICRON CMCs and RelaySimTest. This software allows the whole test to be controlled from one end of the line. CMGPS 588, a GPS controlled time reference, had been used to enable synchronized injection.

Testes de esquemas de teleproteção da proteção de distância devem verificar ambos os relés simultaneamente, incluindo o seu link de comunicação.
Esse vídeo mostra um teste real de uma linha de transmissão de 110 kV. A proteção ficou fora de serviço por apenas uma hora. O teste completo pode ser realizado de forma tão eficiente, pois utilizou os CMCs da OMICRON e o RelaySimTest. Esse software permite que o teste seja controlado de um único extremo da linha. O CMGPS 588, uma referência de tempo controlada por GPS, foi usado para permitir a injeção sincronizada.

Testy układów [uwspółbieżnienia] zabezpieczeń odległościowych wymagają jednoczesnego sprawdzenia obu zabezpieczeń i połączenia między nimi.
Film przedstawia faktyczny test linii napowietrznej 110 kV. Zabezpieczenie wyłączono z eksploatacji na ledwie godzinę. Cały test można było przeprowadzić tak sprawnie dzięki użyciu testerów OMICRON CMC i programu RelaySimTest. Pozwala on sterować całym testem z jednego końca linii. Aby podać sygnały synchronicznie, użyto wzorca czasu sterowanego przez GPS, urządzenia CMGPS 588.

Видеоролик реального испытания воздушной ЛЭП на 110 кВ. Система защиты бездействовала всего один час. Такой эффективности мы добились благодаря испытательным комплектам CMC и ПО RelaySimTest производства OMICRON. Это ПО позволяет управлять всем испытанием с одного конца линии. Для синхронизации установок использовался CMGPS 588, блок синхронизации под управлением GPS.
