Injecting faults in protection relays to determine if it is functioning correctly is commonly used.
The software EUROVECTOR, WINDOW based and is designed as a graphic tool to facilitate fault testing. It can also record, print, etc., the different types of faults. To perform the task, there are two basis modules which cover the two different concepts to edit and define the fault sequence:

- Vector Module, a Graphic vector that represents the six vectors applied (three voltages and three currents) with their corresponding phase angles. Sequences of up to 10 successive faults can be edited.

- Impedance Characteristics Module, to define a a fault or faults in an Impedance plan previously produced. Available as a Mho or quadrangular representation in numeric or graphic form.

APPLICATION

- To test the function of a protection system or relay, in situations of succesive faults.
- Test distance relays in as many test points as required setting the parameters graphically over an impedance diagram.

CHARACTERISTICS

- Windows based.
- Different test can be easily defined in vectorial or impedance plane representation, in numerical or graphic mode.
