Compatible with the SW2001 High Voltage Multiplexer
Noise-resistance through high-frequency CT
AC and Surge dual-mode partial discharge detection
Discover latent insulation defects in motor windings with the AC PD test (IEC 60270 and IEC 60034-27-1 compliant) and surge PD test (IEC 61934 Ed. 2 and IEC60034-27-5 compliant). The ability to select between the two types of PD tests allows you to customize your inspection process to the specific needs of each motor, maximizing the detection of latent failures.
Partial discharge testing on production lines with a microwave antenna is highly susceptible to noise interference. Using a high-frequency CT minimizes noise, simplifies installation by reducing the need for precise positioning, and thus prevents measurement errors.
Complex testing environments often come with high noise which are difficult to reduce.
