High Voltage Laboratory
Multiple labs with different size for medium and high voltage products available for:
• Dielectric short- and long-term tests
• AC Lightning and Switching Impulse Voltage Tests
• Combined Voltage Tests
• Partial Discharge Measurement
• RIV Tests with the following maximal parameters:
Impulse Testing
| Max. Volt. | Standard/Remarks | |
| Lightning Impulse | 3000 kV | Indoor |
| Switching Impulse | 1800 kV | Indoor |
| A.C. Testing: | 1200 kV | Indoor (Partial discharge testing, noise level < 1 pC) |
| 1800 kV | Outdoor | |
| D.C. Testing: | 1200 kV | Indoor |
High Power Laboratory
• Switching capability tests
• Short-circuit making and breaking tests
• Short-circuit current carrying and withstand tests
• Capacitive tests, Tests of arcing due to internal fault
• Bus-transfer current tests.
Max. Testing Parameters Lab 1
| 2 Generators with max. power of 6400 MVA for 3-phase direct test or short-circuit current for 3 sec. | 11 kV | 216/80 kA |
| 2 Synthetic circuits with max. TRV | 1150 kV | |
| Single-phase short-circuit current | 35 kV | 205/76 kA |
| 20 kV | 270/100 kA |
Max. Testing Parameters of Lab 2
Dedicated especially to MV products 1 Generator with max. power of 1250 MVA.
Note: The generators of Lab 1 and Lab 2 can be switched in parallel to get higher output. That means that also short-circuit current tests of surge arresters with pre-failing can be performed.
Impulse Testing Laboratory
Surge Arresters Testing Capabilities – Impulse Current Testing
| Lightning Current Impulse (8/20 μs) | 40 kA |
| Switching Current Impulse (30/60 μs) | 3 kA |
| Steep Current Impulse (1/2 μs) | 20 kA |
| High Current Impulse (4/10 μs) | 150 kA |
| Long Duration Current Impulse | 5 kA / 5 ms / W = 348 kJ |
