The individual harmonics and...

Power Quality Events Via PAS Software DIREC TIO VOLTAGE TION INTERRUP

The EM920 provides state-of-the-art fast transient recording capability. Transient pulses as short as 17 microseconds can be reliably recorded and analyzed. The EM920 can record such short pulses by a separate electronic channel with a sampling rate of 1024 samples/cycle. The transient amplitude is recorded relative to the ground in accordance with the strict definitions of power quality standards (EN 50160). The instrument can measure transient pulses with an amplitude of up to 2 kV (withstands up to 6 kV). Four voltage waveforms (3 phases and neutral relative to the ground) are recorded...
