Description
The SVERKER 900 relay and substation test system is the engineer’s ultimate toolbox, addressing the increasing need for three-phase testing in electrical distribution substations, renewable power generation stations, and industrial applications. It has a powerful combination of current and voltage sources and a range of measurement possibilities.
The SVERKER 900 is specifically designed for basic, manual three-phase secondary testing of protection devices. In addition, you can perform various primary tests as the current and voltage sources can be connected in series and/or parallel to give you up to 105 A AC or 900 V AC output.
The instrument’s three current sources and four voltage sources can be individually adjusted with respect to amplitude, phase angle, and frequency. The fourth voltage source allows for testing of numerical relays that need a reference voltage simulating the busbar. Operating the relay tester is also incredibly easy thanks to its intuitive user interface presented on an LCD touch screen.

Frequently Asked Questions
Can the protection relays used in electrical distribution systems that operate at 400 Hz, e.g., in shipyards, be tested with a SVERKER900?
400 Hz power systems are sometimes encountered in marine applications and, far more frequently, in the aeronautical industry. These high-frequency systems are favoured because transformers and other components operating at this frequency are smaller and lighter than their 50/60 Hz counterparts. The SVERKER900 range can produce voltages and currents from DC to 600 Hz.
What is the licence cost for software?
There are two parts to the fee structure – one is the software on the SVERKER screen that is categorised into three types: Basic (consists of Main and Prefault-Fault), Advanced (consists of Basic, CT Magnetization, Ramping, and Sequencer), and Expert (consists of Advanced and Impedance). The second is the reporting software, which is an additional cost but is optional. The SVERKER Viewer is a PC-based software that can create graphical test reports in PDF format. The PDF test report is created by opening a saved test file (on a USB drive) from the SVERKER900.
Can you test recloser relays? How does it interface?
It is possible to test recloser relays using the different tools available in the SVERKER software. In particular, the sequencer tool simplifies the job of testing recloser relays and recloser controls.If the recloser relay is inside a recloser control or in the field, you may use a tool called the Megger Electronic Recloser Test Simulator (ERTS) to interface with the recloser control. The ERTS allows testing of the recloser relay directly in the controller without disconnecting the relay analogue inputs or binary inputs or outputs.
Do you have test plans for my relays in your software?
The SVERKER software does not offer any test plans for relays. This software is supposed to be used for manual and semi-automated testing.
