A new generation of advanced test equipments for relays, energy meters, transducers and power quality meters
DRTS 33: with 3 Current and 3 Voltage generators plus 1 battery simulator
DRTS 33 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.
Its powerful current outputs (3 x 32 A at 420 VA) and voltage outputs (3 x 300 V at 100 VA) allow to test 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 33 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 to control 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.
