Megger SVERKER900 3-Phase Relay & Substation Test System - Standard

Megger

Upgraded version of the SVERKER900 Basic Kit Powerful, multifunctional relay test system Built-in touchscreen Megger SVERKER900 3-Phase Relay & Substation Test System - Standard Details Note: there are three versions of the Megger SVERKER900 Test Set available: Basic, Standard and Expert. This is the Standard kit, which includes the following (new features compared to the Basic Kit are outlined in bold): 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 Megger's SVERKER900 is a powerful, multifunctional relay and substation test system designed to give professional technicians all the tools they need to perform secondary and primary testing of relay protection within electrical distribution substations, renewable power generation stations and industrial applications. With the SVEKER900, you'll have everything you need for three-phase secondary testing of protection devices, plus primary testing. You can use this unit for a wide variety of tasks including commissioning and maintenance of distributed/generator power in substations, testing electromechanical, static and numerical protection relays and much, much more. Portable with a built-in carrying handle for easy transportation, the SVERKER900 can be configured to your specific application using a fast response, full colour built-in LCD touchscreen. A wide variety of inputs and outputs cater for practically any testing appliation. The Megger SVERKER900 Relay Test System is suitable for use with a huge range of relays, including: distance protection/under impedance, overfluxing, synconising/synchornism-check, undervoltage, directional power, undercurrent/underpower, loss of field, negative sequence overcurrent, phase sequence voltage, thermal, overcurrent/ground fault, power factor, overvoltage, DC overcurrent and a wide variety of other relays. 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 Megger SVERKER900 Three-Phase Relay/Substation Test System Key Features Full toolbox for substation 3-phase testing Three current and four voltage sources Standalone functionality Rugged and reliable with integrated carrying handle for use in the field Generation 900V and 105A in single-phase mode Secondary and primary testing Fast response LCD colour touchscreen What's Included?
