The Megger SVERKER750 is the engineer's toolbox for secondary testing of protective relay equipment.

The SVERKER750 can be used to test a wide variety of equipment, including overcurrent relays, inverse time overcurrent relays, undercurrent relays, ground fault relays, directional overcurrent relays, undervoltage relays, power factor relays, time-delayed relays and much, much more.

Whether you're new to the SVERKER family or have used other models such as the SVERKER650 in the past, the SVERKER750's intuitive interface with local layout and built-in digital screen make the system as simple to use as possible. Once configured, the SVERKER750 can be used to measure and display time, voltage, current, Z, R, X, S, P, Q, phase angle and cos φ.

You can also use the Megger SVERKER750 for a wide variety of other applications including plotting excitation curves, current/voltage transformer ratio tests, burden measurements, impedance measurements, efficiency tests, polarity tests and more.

For added convenience, select SVERKER750 models even come with a useful carrying handle for easy porting from test to test.

Megger SVERKER750 Feature/Benefit Breakdown

The following table outlines the functionality of the Megger SVERKER750.

1 - Set of Resistors Made for fine adjustments and regulation of current and voltage
2 - Start and Stop Conditions The timer's start and stop inputs respond to changes, voltage or contact closing/openings. The timer's start input is also used when testing auto-reclosing relays to synchronise two or more SVERKER units and to start generation with an external signal
3 - Display Shows time, current, voltage and other parameters. Also used to make settings (access setting mode by pressing MODE button)
4 - Freeze Function (HOLD) Makes it possible to measure voltage and current as short as a quart of a mains voltage period by saving a reading on the display. Voltage and current readings are frozen when the timer stops. If it doesn't stop, the reading present when the current was interrupted is frozen on the display.
5 - Make/Break Contact Changes state automatically when a test is started. Can be used (for example) to synchronise two or more SVERKER units, other external equipment or to switch the voltage applied to the protective relay equipment back and forth between faulty and non-faulty.
6 - Ammeter and Voltmeter Current and voltage are measured by the built-in ammeter/voltmeter. Resistance, impedance, phase angle, power and power factor can also be measured. Reading appear on the display. These instruments can also be used to take measurements in external circuits. The voltmeter can also be used as 2nd ammeter (when testing differential relays, for example, using CSU20A). Current and voltage can be displayed either as amperes or volts or as percantages of a given voltage or current (the present settings of the protective relay equipment, for example).
7 - Current Source Provides 0-250A AC, 0-250V AC or 0-300V D, depending on the ouput being used. Setting are made using the main knob. The readings of current, voltage and other entities appear on the display. The start switch is used to turn the current source on and off. When time is being measured, this is done in synchronisation with the timer.
8 - Auxiliary Voltage Source Provides 20-220V DC in two ranges. Equipped with overload protection and separate from the other outputs. Used frequently to supply the object being tested.
9 - Status Indicator The timer's start and stop inputs are each equipped with indicator lamps which, when lighted, indicate a closed circuit (useful for detecting contact closings/opening) or the presence of voltage. These indicator lamps make it possible (for example) to check circuits before starting a measurement cycle.
10 - Timer Inputs The timer has separate start and stop inputs, and it can be used to measure both external cycles and sequences initiated by the SVERKER. The measured time appears on the display. Each input can be set to respond to the presence of absence of voltage (AC/DC) at a contact.
11 - Start Switch Controls the turning on and off of the current source and timer. Can be set to one of four states. ON+TIME. Starts generation and timing simultaneously. Used to test over current, voltage or other parameter relays. Generation continues a) until the protective relay equipment operates and stops the timer or b) until the maximum time expires or the start switch is released if time-limited generation has been selected.
OFF function turns of the current source, wherupon generation is interrupted. ON function turns on the current source in the generating state.
OFF+TIME function interrupts generation and starts the timer simultaneously. Used when testing current, voltage or other parameter relays. The timer is stopped when the protective relay equipment operates. When automatically reclosing is set to be tested, the SVERKER can be set to start a new generation when the timer's start input is activated by the closing command.
12 - Computer Interface (USB) Serial port for communication with PC and SVERKER Win PC software
13 - Tripping Indicator Lights when a stop condition is fulfilled to indicate operation of the protective relay equipment. If the test being conducted incorporates timing, this indicator starts to blink when relay operation occurs.
14 - Main Knob Used to set current output from the current source
15 - AC Voltage Source Since the AC voltage source is separated from other outputs, it is set independently of the current source. The AC voltage source is intended primarily for the relay protection equipment's voltage input
