About Automatic relay test set DRTS 33

Adiradh offers the ISA DRTS 33 Automatic Relay Test Set, an advanced three-phase secondary injection testing system designed for testing and commissioning electrical protection relays. It generates three independent current outputs and three voltage outputs simultaneously, allowing accurate testing of different types of protection relays.

The DRTS 33 supports testing of electromechanical, solid-state and numerical relays. Moreover, it can test energy meters, transducers and power quality meters. The system delivers current outputs up to 3 32 A and voltage outputs up to 3 300 V, with output accuracy better than 0.05%.

Additionally, the equipment supports IEC 61850 communication, USB and Ethernet interfaces. It can operate through its front-panel colour display or optional TDMS testing software. Therefore, it is suitable for electrical substations, power utilities, transmission networks and industrial electrical maintenance.
