This is the Megger SVERKER900, the ultimate engineer's toolbox for secondary and primary testing of substations, renewable power generation stations and industrial applications.

Powered by a fast-response, easy-to-use touchscreen for quick and easy configuration of all procedures, the Megger SVERKER900 can be used for a wide variety of tasks including testing protection relays, plotting current transformer excitation curves, polarity (direction) tests, primary injection in switchgear (both three and single phase), wiring checks and much, much more.

The SVERKER900 is equipped with three current and four voltage sources, allowing it to be used in either series of parallel, catering for current to 105A (AC) or 900V (AC) output. All sources can be individually adjusted with respect to their amplitude, phase angle and frequency, while the fourth voltage source can be used to test numerical relays which need a reference voltage simulating the busbar.

For added convenience, the SVERKER900 comes built inside its own carrying case for transportation and protection of the unit when moving from test to test. The lid of the case is also uniquely designed - it houses a selection of jumpers in specific holders as well as a touch screen pen and a quick reference guide for ease of use.

With the SVERKER900, there's no need to use a computer when testing. The tester's unique interface with fully configurable options using the touchscreen, plus integrated datalogging capabilities, make it ideal for both measuring and logging data. When done testing, simply connect the SVERKER900 to PC via USB connection to transfer your files and data in standard CSV format (compatible with Microsoft Excel).

Megger SVERKER900 Interface Breakdown

The following table outlines exactly what's included on the SVERKER900's front interface.

1 - Binary Inputs (1-4) The binary inputs are independtly programmable gate circuits that permit simple selection of the desired mode for voltage or contact monitoring operations. Binary input 1 has a selectable threshold voltage
2 - Extra Timer With separate start/stop inputs, the timer can be used to measure both external cycles and sequences initiated by the SVERKER900. The measured time appears on the display. Each input can be set to respond to the presence of abscence of voltage (AC/DC) at a contact
3 - Binary Output The binary output is used to simulate normally open/normally closed contacts for testing breaker failure schemes, or similar power system operations. In addition it may also be used to switch AC/DC voltages and currents
4 - Current/Voltage Current and voltage are measured by the built-in ammeter and voltmeter. Resistance, impedance, phase angle, pwer and power factor can also be measured. Readings appear on the display. These instruments can also be used to take measurements in external circuits
5 - Current Generators The current generators can be used separately, in parallel or series.
The current generators deliver maximum compliance voltage to the load constantly during the test, and range changing is done automatically, on-the-fly, under load.
6 - Voltage Generators The voltage generators can be used separately, in parallel or series
7 - USB For external keyboard, mouse, saving test data and for updating internal SW
8 - Mains Inlet  
9 - Ground (Earth) Connection  
10 - On/Off Switch  
11 - Ethernet Port For authorised service actions
12 - Touch Screen 5.7" full colour LCD
13 - Control Knob For setting of current, voltage and other parameter values
