Protections Relay Test Introduction  

DV1512A2NCI was developed to satisfy specific ENEL requirements for A2NCI unified protections testing  device. LogicLab designed and developed an equipment that, according to modern protection system test  requirements, can easily satisfy user's needs.

The device is a single phase  voltage and current generator (two single channels), that can switch current flow on four different output (IO, IR, IS and IT) and voltage on two different output (VR and VO); the device is also equipped  with four digital input and four output relays.

DV1512A2NCI is equipped with connection cables to A2NC protections  and two programs providing the complete management of the system. The single test program interface allows you to  use the device as a sinusoidal voltage and current generator or generic wave shape. It also allows you to develop your personal testing programs. You can test any kind of protection device not only those  already set up by the automatic program, that tests  DV901A2NCI, DV910A2NCI, DV920A2NCI e DV925A2NCI protections.

Once you choose the device, following protection test configuration, the DV1512A2NCI operates automatically; protection configuration may be brought in from Excel file. More generally, it is  possible to test a single trip threshold, thus making the devices suitable to  different protections.

This device can satisfy highest signal precision and quality requirements. Software allows you to profit by all the possibilities offered by test equipment.
