Description

The digital relay and meters test system type DRTS 34 is a programmable and automatic current and voltage source, that permits for the automatic test of digital protection relays, such as those used in Medium and High voltage networks, and of energy meters, power quality meters and transducers. The test set can be controlled locally, without the connection to a PC, by means of a graphical colour display, a keypad, a rotary switch and function keys. The unit can be controlled also by and advanced test software running on a PC.

The DTRS 34 has 3 current generators, 4 voltage generators and 1 battery minulator.

Its powerful current outputs (3 x 32 A at 430 VA) and voltage outputs (3 x 300 V at 100VA) allow you to test any type of relay, including older electromechanical relays that draw higher power.

These test equipment include the IEC61850 protocol interface for testing relays with the Ethernet-based communication protocol.
