High-power testsReliable test resultsat extreme currents and voltagesAt the high-power laboratory, we test your high andmedium-voltage equipment with respect to the followingproperties: thermal and dynamic short-circuit performance making/breaking and insulation capacity at short-circuitconditions operational behavior.The three available short-circuit generators can be connected flexibly. Hence, several specimens can be tested inparallel, or a total short-circuit current of up to 100 kA at20 kV can be generated for individual tests. Voltage isadjusted to the particular requirements by power transformers. For high-voltage products, synthetic tests withvoltage and current injection methods are applied as well.The synthetic test circuits are arranged in a flexible manner, so that the capacitive breaking capacity can be testedat 50 and 60 Hz. We can also test bus-transfer currentsaccording to the latest requirements of IEC 62271-102.We also have a laboratory for basic research, where currents of up to 80 kA at 50/60 Hz can be generated bycapacitor banks and synthetic voltages of up to 120 kV areavailable. This laboratory therefore offers an attractive andflexible alternative to tests with generators.Performance data of the high-power testing laboratoyMaximum generator output6,400 MVAMaximum short-circuit current (single and three-phase)100 kA/80 kAMaximum short-time withstand current 3 s80 kAMaximum voltage for synthetic tests1,150 kVFrequency50/60 Hz*Characteristics of the laboratory for basic physical studiesMaximum short-circuit current (one phase)80 kAFrequency50/60 HzMaximum voltage for synthetic tests120 kV* 60 Hz to 20 kA4

Did you know that we can run short-circuit and pressure relief tests including pre-failing on highand medium-voltage surge arresters in conformance with standards?Emulating an overload in a surge arrester in conformance with standards is a technical challenge, especiallyfor type B arresters (without gas volume). The highpower testing laboratory is one of the few facilities inthe world that is able to carry out this test on all arrestertypes in accordance with IEC 60099-4. Two test circuitsare combined into one: the pre-failing test circuit withup to 30 A at voltages up to 180 kV, and the high-current circuit, which can provide a voltage up to 35 kV andcurrents up to 65 kA.5

High-voltage testsShort- and long-term stressat maximum voltagesThe high-voltage testing laboratory provides a wide rangeof dielectric tests for short and long-term stress. It has twoindependent testing halls, several smaller laboratories, andan open-air testing area for voltage tests. We provide: lightning impulse voltage tests alternating voltage, direct voltage, andswitching impulse voltage tests combined voltage tests.A separate laboratory provides testing and measuringequipment tailored specifically to the medium voltagelevel. In parallel with the voltage tests, other examinationscan be performed, among them measurements of conventional (IEC 60270) and UHF partial discharge (PD), radiointerference voltage (RIV), measurements of the dissipationfactor and capacity as well as rain tests.We can also carry out dielectric tests on post and overheadline insulators with tower and line simulation. Small laboratories are also available for testing materials and insulation.The open-air testing area permits long-term tests of insulation materials under DC and AC to simulate aging processes. The large test halls of the high-voltage test laboratoryand the medium-voltage hall are shielded. This allowssensitive PD measurements with a very low noise levelof less than 1 pC. The high-voltage test laboratory alsopermits testing of bus-charging currents of disconnectorsfor gas-insulated switchgear.Maximum test voltagesAlternating voltage (50 Hz)1,200 kV,open air up to 1,800 kVLightning impulse voltage (1.2/50 μs)3,000 kVSwitching impulse voltage (250/2,500 μs)1,800 kVDirect voltage1,200 kVMaximum impulse currentsMaximum lightning impulse current (8/20 μs)40 kAMaximum switching impulse current (30/60 μs)3 kAMaximum high impulse current (4/10 μs)150 kAMaximum rectangular impulse current (2 ms)5 kA6

Incidentally we can also perform the technically demanding composite voltage tests in accordance with standardsat our high-voltage testing laboratory in Berlin.»Composite Voltage Tests« or Superimposition Testsinvolve two superimposed voltage waveforms that aredecoupled from each other and are performed on asingle specimen. We can run tests with up to 550 kV DCvoltage and a simultaneously superimposed lightningimpulse of up to 1,550 kV. As much as 1,175 kV is possible for switching impulse voltage. The tests can also beperformed with a heated conductor.7

Mechanical testsand temperature riseTests of mechanical functions, temperature rise,and environmental propertiesThe mechanical testing laboratory examines and analyzesmechanical functions and environmental properties. Modern measurement technology enables the precise, partiallyautomated logging and analysis of measured data.Comprehensive facilities with control and measuringsystems allow a wide range of tests and examinations,such as:The mechanical test laboratory comprises a high-currentfacility for temperature rise tests at 50/60 Hz AC and DC.Several temperature chambers make it possible to performclimatic tests. Endurance tests are carried out in the hall,which is equipped for this purpose. High-current tests and temperature rise testsThe powerful, cam- and frequency-controlled vibration testsystem with vertical and horizontal acceleration permits thedetermination of break, tension, and compression parameters, testing of the equipment’s mechanical service life,and transport testing.
