This laboratory is able to perform tests from 10 V to 850 V and up to 4,000 A, when coupled with one regulator transformer.Medium Power Testing PortfolioShort time current withstand up to 80 kA rms for3 seconds and 160 kApDisconnector busbar transfer current up to 4,000 AEarthing switch breaking and making of inductive currentsTechnical CapabilitiesTransformers: 2 x 23 MVA, 2,000 VRegulator transformer:10 V to 850 V and up 4,000 APower factor < 0,15 HIGH VOLTAGE TESTING High Voltage Testing The high voltage testing laboratory offers several possibilities for short and long term insulation testing, and is equipped with three power frequency transformers and one impulse generator bank. All tests can be performed also under rainy conditions for outdoor equipment. The laboratory provides the necessary tools to measure Radio Interference Voltages (RIV) as well as Partial Discharge (PD).High Voltage Testing PortfolioAC power frequency testsSwitching impulse testsLightning impulse testsDC dielectric testsCombined voltage tests (BIAS)Chopped wave testsTechnical CapabilitiesPower frequency - up to 1 MV 50 HzLightning impulse - up to 2.5 MV (1.2 μs / 50 μs)Switching impulse - up to 1.6 MV (250 μs / 2,500 μs)Direct voltage - up to 1 MV DCPartial discharge - up to 750 kVRIV testing - up to 550 kV TEMPERATURE RISE TESTING Temperature Rise Testing This test laboratory can simulate the impact of the equipment on the environment e.g. the energy losses or radiation under nominal current applications. It is made of two independent, parallel testing rooms with its own current generator and allows to record up to 200 x PT1000 temperature sensors together. The ambient temperature can be controlled up to 40 °C.Temperature Rise Testing PortfolioShort term temperature rise testsLong term temperature rise testsCalculation of temperature rise values based on the resistance measurement of the current transformersTechnical CapabilitiesTests in AC – Single-Phase (50/60 Hz) - up to 50 kATests in AC – Three-Phase (50/60 Hz) - up to 10 kATests in DC - up to 4 kA CLIMATIC & MECHANICAL TESTING Climatic & Mechanical Testing The climatic chamber is equipped with one room, which can reproduce extreme environmental conditions and temperatures from -60 °C to +60 °C. Additionally the laboratory is equipped for leakage measurement by accumulation for gases such as SF6, CF4 or g3 – green gas for grid.Climatic & Mechanical Testing PortfolioIcing testsMechanical testsLeakage measurementsTechnical CapabilitiesTemperature range: -60 °C to +60° CTesting room dimensions: 11 x 6 x 6.8 m (D x W x H) Contact Us CERDA is located in Villeurbanne, Lyon.
