Electronic Specialties 191 Relay Buddy Pro Test Kit

Product Information

In 2012, an ad hoc working group – AHG2 “New protection requirements for the smart grid”– was formed and it submitted its report to TC 95 in 2014. This identified a need for revising some of the existing standards and for developing new standards taking into account the high penetration of distributed generation, which is posing new protection challenges. Revisions of IEC 60255-1, IEC 60255-26, and the new functional standard IEC 60255-181 were identified as high priorities.

The Megger SVERKER780 relay tester is equipped with every measurement function you'll need, all shown in real time on the built-in LCD digital display. This powerful measurement section can display (in addition to time, voltage and current) Z, R, X, S, P, Q, phase angle and cos φ. An integrated voltmeter and ammeter are included for measurements, with the possibility to use the voltmeter as a second ammeter (ideal for testing differential relays).

IEC61850is now successfully established as the standard for communication in electrical power systems. Using standardized protocols such as GOOSE, Sampled Values and MMS, devices and systems can seamlessly exchange data, commands and measured values. When connected to a common network, equipment from different manufacturers can therefore communicate directly with one another. No additional effort is required for hardwired binary signals and the system can be easily re-configured if required. Standardization on IEC61850also makes it easier to carry out scheduled maintenance tests. When implementing fully digital substations it's almost impossible to avoid this standard.

Megger SVERKER780 Relay Test Set Key Features

The SVERKER650 is compact and portable enough to easily be transferred from testing point to testing point and is supplied as standard with a rugged carrying case. Megger SVERKER650 Terminal/Function Breakdown terminal and the other probe on the NC Terminal. Make sure that you read a resistance of near 0Ω. If you do, then These diagnostic methods determine whether a relay's coil is collapsing while switching positions during operation. Bonetti, Andrea, Murty V.V.S.

No problem with the SVERKER780 - hook the relay tester up to your PC via the built-in serial connection to export your results into Excel documents or use Megger's SVERKER Win software (sold separately) to create fully customisable reports and log data in real-time. Megger SVERKER780 Feature/Benefit Breakdown

With Megger SVERKER units, you'll have everything you need to test practically any single-phase relay protection. This relay test set is suitable for use with overcurrent, inverse time, undercurrent, ground fault, directional overcurrent, directional ground fault, overvoltage, undervoltage, directional power and a wide variety of other single-phase protection. It's also suitable for use on three-phase protection - just use the SVERKER780 on one phase at a time or alternatively this relay tester is also suitable for use on phase-shifting protective relay systems plus automatic reclosing devices. Settings-based protection testing focuses on the protection functions and the associated set values of the individual protection relay. Modern protection relays offer thousands of settings which is why automated testing is far superior to a manual approach. TestUniverse provides you with an extensive range of options in terms of standardization and automation, including fully automatic creation of test reports. With the aid of test plans, you can carry out testing with maximum efficiency. Combined with the immense functional range, our testing software also gives you the necessary flexibility to test protection relays and other secondary assets in detail. Relay testing provides an affordable solution to protect important electrical equipment components and avoid the expense of downtime or repair associated with equipment failure. Both kits are basically identical - they are powerful, multifunctional relay testers which can easily be ported from testing point to testing point. The main difference between the 780 and the 750 is the 780 also includes continuous phase shift and adjustable frequency functions as well as a variable voltage source.Specifications are valid at nominal input voltage and an ambient temperature of +25°C (77°F). Specifications are subject to change without notice. Environment

The standards are being developed and published by the Maintenance Team 4 (MT4) of IEC Technical Committee 95 (TC 95): “measuring relays and protection equipment”. The scope of TC 95 is the standardisation of measuring relays, protection equipment, and protection functions embedded in any equipment or systems used in various fields of electrical engineering covered by the IEC, including combinations of devices and functions that form schemes for power systems protection. TheTC 95 scope includes control, monitoring, and process interface related functions and equipment used with protection systems (such as automatic reclosing, fault location, teleprotection or process data interfaces, and fault recording); as well as protection and protectionrelated functions of distributed energy resources (DER) or inverter-based resources (IBR).

Megger SVERKER780 Feature/Benefit Breakdown

To achieve a high degree of automation in protection testing, you need both adaptable test templates for protection relays from different manufacturers and the possibility to flexibly combine individual test modules in test plans. Efficiency can be raised further by defining uniform standards for testing protection relays. Fully automated documentation of the test results is also a basic requirement as this involves considerable effort when performed manually. Our Protection Testing Library (PTL) and the OMICRON Control Center (OCC) allow you to use test procedures that are individually customized to suit your needs, which can be carried out almost fully automatically. Compared to manual protection testing, the testing effort can be reduced by up to 80 percent. The Megger SVERKER650 is a powerful, compact and simple-to-use relay test set suitable for testing a wide variety of power, voltage and current relays. when the relay isn't energized; thus, there is an extremely high impedance between the 2 terminals.
