Now in its third generation, the
APTS three-phase protection relay test set is the flagship
multipurpose relay test set manufactured by RES. The APTS utilises
the latest digital signal processing based waveform synthesis
techniques coupled with advanced low-noise switching amplifier
technology. This combination enables the APTS to deliver precision
waveforms at the highest output power available in a portable
lightweight computerised test set anywhere. The highest burden
single & three-phase electromechanical relays as well as the
latest microprocessor based relays can be tested directly and
without the need for additional accessories or amplifiers.
