Megger Sverker900 Standard

The Megger SVERKER 900 Relay and Substation Test System is the engineer’s ultimate toolbox that addresses the increasing need for three-phase testing capability in electrical distribution substations, renewable power generation stations and industrial applications. The Sverker 900 is the ideal instrument for use in applications that include commissioning and maintenance of distribution substations and generator installations; testing of electromechanical, static and numerical protection relays; plotting current transformer excitation curves; burden measurement for CTs; polarity/direction measurement; impedance measurement; single and three-phase injection testing in switchgear; checking SCADA annunciation and measurement values; and performing network measurements. To complement the current and voltage generators, the SVERKER900 features a large colour touchscreen that provides an intuitive user interface and a powerful internal processor that eliminates the need to use an external computer for most types of manual and semi-automatic testing. Full manual control and configuration is also supported and, in addition to the touchscreen, the instrument is provided with a large rotary knob that can be configured as required to control the current and voltage generators. Test configurations and test results are stored in internal non-volatile memory and can be readily transferred to and from a PC via the instrument’s USB port. The intuitive user interface is presented on the LCD touch screen. It has a powerful combination of current and voltage sources and a versatility of measurement possibilities. FEATURES The toolbox for substation 3-phase testing. Three currents and four voltages. Stand-alone functionality. Rugged and reliable for field use. Generation of 900 V and 105 A in single phase mode. Secondary and primary testing.
