PSW research and testing laboratories are:
• Accredited according to IEC/ISO 17025
• Member of PEHLA (Member of STL)

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:

Max. Volt. Standard/Remarks
Impulse Testing:
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. at              11 kV         216/80 kA
2 Synthetic circuits with max. TRV          1150 kV
Single-phase short-circuit current at        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
