DRTS 64 is the leading edge, most powerful and accurate relay, energy meters (class 0.1), and transducers test set manufactured by ISA. The locally and PC-controlled test set generates high precision (0.05% accuracy) signals using multiple DSP technology. Four hardware configurations are available:
- DRTS 66: with 6 Current 6 Voltage generators plus 1 battery simulator
- DRTS 64: with 6 Current and 4 Voltage generators plus 1battery simulator
- DRTS 34: with 3 Current and 4 Voltage generators plus 1battery simulator
- DRTS 33: with 3 Current and 3 Voltage generators plus 1battery simulator
Its powerful current outputs (3 x 64 A at 860 VA) and voltage outputs (3 x 300 V at 100 VA) allow testing any type of relays including electromechanical relays.
The test sets integrate the IEC 61850 protocol interface for testing relay with Ethernet-based substation communication protocol.
DRTS 64 can be operated directly from the front panel by means of a large color graphical display, a rotary selector, a keypad, and function keys. Two PC interfaces, USB and Ethernet, allow controlling the test set with the advanced testing software TDMS. It can also be operated by the optional Local Touch Control (touch screen) module that can be used attached or detached from the test set.
