Prüfungen

We carry out technical tests for you as part of a development project or as an independent service. With the aim of achieving a positive test result for you in a short time, we also accompany and monitor tests at accredited institutes worldwide and offer the following services:

• Outlooks, reports, and expert opinions on the planned test
• Organization, transport, and logistics of the test objects, including international ones
• Technical support of the test object during the test process
• Documentation of the test procedure
• Short-term design adjustments and modifications to the test object (assembly, welding, milling, turning, drilling, potting, 3D spare parts)
• Acquisition of additional measured values ​​(pressure, speed, temperature, etc.)

Special tests for switchgear and controlgear:

• Dielectric tests of rated power frequency withstand voltage, switching impulse withstand voltage, and rated lightning impulse withstand voltage
• Heating tests and resistance measurements of the main circuit according to IEC 62271–1
• Helium integral tests as leak tests for gas containers (GIS, GIL)
• Compressive strength tests
• Electrical partial discharge measurements on components in the laboratory and on-site
• Mechanical endurance of electrical, magnetic, hydraulic, and stored-energy drives
• Single- and multi-pole short-circuit tests
• Arc fault tests
• Seismic tests

We support the following type tests:

• Circuit breakers according to IEC 62271-100
• Earthing and disconnecting switches according to IEC 62271-102
• Load-breakers and circuit-breakers
• Factory-assembled compact substations according to IEC 62271-202
• Switchgear according to IEC 62271-200, -203
• Further tests according to DLT, GB, GOST, IEEE, GL, and ANSI upon request
