Product description The SVERKER 750 and SVERKER 780 relay testing sets are engineer tools. The control panel has a logical layout, making it familiar to users of the SVERKER 650 and allowing immediate operation. These devices are primarily designed for secondary testing of protective relay equipment. Almost all types of single-phase protections can be tested. You can also test three-phase protection by testing one phase at a time, as well as various systems of protective relay connections requiring phase shifts and reclosing devices.
These devices feature many functions that make relay testing more efficient. For example, they have a powerful measurement section capable of displaying, besides time, voltage, and current, Z, R, X, S, P, Q, phase angle, and cos φ. The voltmeter can also be used as a second ammeter (e.g., during differential relay testing). All values are displayed on a convenient, easy-to-read screen.
You can also effectively test directional protection equipment using the built-in variable voltage source. In SVERKER 780, this also includes continuous phase shifting and adjustable frequency, as well as easy testing of reclosing devices.
Since the compact SVERKER weighs only 18 kg (39 lbs), it is easy to move from one location to another. Additionally, two or more SVERKER devices can be synchronized, enabling the use of a basic three-phase testing set.
Designed according to EU standards and other personal and operational safety standards, the SVERKER 750 and 780 are also equipped with a serial port for communication with personal computers and SVERKER Win software.
