Surge protection device tester EMC Partner AG
IEC61643, IEC61051

Surge Protection Devices (SPD) are also known as Transient Voltage Surge Suppressors (TVSS). These devices can comprise a complex arrangement of varistors, transorb diodes and gas arresters. The function is to divert lightning surge energy away from electrical or electronic equipment. They are activated by the steep voltage impulse generated by a lightning strike and are designed to conduct tens of thousands of Amps in impulse energy. Typical impulse tests for SPD devices include energy absortion (8/20us or 10/350us), duty cycle (8/20us), Clamping voltage (8/20us) and Combination Wave Tests for devices connected in the AC power main.
EMC PARTNER offer a range of instruments from a few Amps up to 100,000 Amps.
All units offer a combination of impulses specific for particular devices whether they are disc varistors, SMD varistors, Gas Arresters or combinations of all.
