Megger SVERKER900 3-Phase Relay & Substation Test System - Expert Details

This is the most advanced Megger SVERKER900 test set available, improving upon the basic and standard versions which are also available.

The Expert SVERKER900 is the only model in the series which includes all of the following:

  • Main Instrument - with timing tests, manual determination of pick-up and drop-out of relay contact and set, inject and measure functions
  • Prefault-Fault Instrument  - perform timing tests which require simulation of a prefault state before fault simulation
  • CT Magnetisiation Instrument - determine the knee point of voltage of the current transformer
  • Ramping Instrument - automatically determine pickup threshold and perform time testing
  • Sequencer Instrument - simulate sequences such as auto recloser, motor start or re-striking earth faults
  • Impedance Instrument (NEW for expert model) - allows testing of relays directly from impedance plane, where the conversion from the impedance into voltage or current is performed automatically by the SVERKER900

About the SVERKER900

Specifically created for testing protection devices, the Megger SVERKER900 is a powerful, multifunctional relay testing set designed to perform basic, manual three-phase secondary and primary testing.

With the SVERKER900, you'll have absolutely everything you need for commissioning and maintenance of distributed and generator power substations, for testing electromechanical, static and numerical relays and even for specific applications such as plotting current transformer excitation curves, performing current and voltage transformer ratio tests and much, much more.

Megger's SVERKER900 is powered by a simple front HMI interface. Using this, the engineer using the relay tester can manually or use the semi-automatic modes to perform tests with everything from making simple primary injections into a switchgear or more complex secondary relay testing all being possible. It's all controlled via a built-in computer and touchscreen system, giving you easy access to the tests you want in absolutely every application.

The front HMI also doubles up as memory storage; the SVERKER900 is able to store your test results directly in its memory, then can be plugged into a PC via the USB port and information can be ported across in CSV Excel format so you can create reports on your PC.

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
