Megger SVERKER 900 Relay and Substation Test System

Megger SVERKER 900 Relay and Substation Test System

The Megger SVERKER 900 is the latest addition to the popular SVERKER range of relay test sets. The SVERKER 900 increases the testing capability of the product range by introducing three-phase testing in electrical distribution substations, renewable power generation stations (PV and wind turbine for example) and other industrial test applications.

In addition to secondary relay testing, the Megger SVERKER 900 will also perform various primary tests, as current and voltage sources can be connected in series and/or parellel allowing outputs of up to 105A AC or 900V AC.

The amplitude, phase angle and frequency of each the three current and four voltage sources can be individually adjusted, whilst  the fourth voltage source can be used for testing numerical relays that require a reference voltage, simulating a busbar.

General test applications for the Megger SVERKER 900 include:

• Commissioning and maintenance
• Protection relays
• Plotting CT excitation curves
• Current and voltage transformer turn ratio tests
• Burden measurement for CT circuits
• Polarity tests
• Impedance measurement
• Single and three phase primary injection
• SCADA annunciation and measurement values
• Wiring check

HMI user interface

The Megger SVERKER 900 is operated using an intuitive human-machine interface (HMI). This comprises of a computer based operating system and touch screen display. The HMI allows for manual or semi-automatic tests to be performed, from simple primary current injection tests to more in-depth secondary relay tests.

The HMI on the SVERKER 900 also eliminates the need for an external computer whilst testing virtually all types of single and three-phase primary and secondary protective equipment found within a substation. It can inject current up to 105A AC whilst boasting a frequency range of 10Hz to 600Hz alongside DC testing capabilty, too.

Moreover, the SVERKER 900 allows for data transfer via a USB port to a computer, where .CSV data can be analysed using Microsoft Excel to create reports.

 Multifunction testing solutions

The Megger SVERKER 900 is available to include multiple test instrumentation in one portable solution; please see the comparison chart below for options available. Using the different test settings, the substation test tool can be used for the following test scenarios:

• Main Instrument
• Timing test
• Manually determine the pick-up and drop-off of relay contact
• General: set, inject, measure
• CT Magnetization Instrument
• Determine the knee point voltage of the CT
• Prefault – Fault Instrument
• Timing test – used mainly to test relays that require a simulation of the prefault state before fault simulation
• Ramping Instrument
• Automatically determine the pickup threshold
• Time testing, e.g when testing df/dt relays
• Sequence Instrument
• Simulation of sequences, e.g auto re-closure, motor starts, re-striking earth fault
• Impedance Instrument
• The impedance screen allows for testing relays directly from the impedance pane, where calculations of impedance into current and voltage is completed by the SVERKER 900
• Prefault and fault test
• Impedance ramping
