Three-phase Secondary Injection: DRTS33
This secondary injection tester has 3 channels and is designed for testing protection relays, energy meters, transducers and power quality meters. This test set is designed primarily for manual control via the HMI; an option is available to link to a computer for remote control.  For testing three-phase differential relays, consider the DRTS66.
Main Features:  
Direct manual control via HMI
Simultaneously available: 3 Current and 3 Voltage plus 1 battery simulator outputs. 
High current outputs: 3 x 32 A, (1 x 96 A)*
High power outputs: 3 x 430 VA, (1 x 1000 VA)**
