To date, around Tester devices,around relay devices have been sold and used by electrical engineers all over the country. The first industrial product of this company entered the market in 2014 and within three years more than 300 relay tester devices were sold to important industrial centers of electricity, oil and gas as well as some universities. Vebko is a science-based company, stablished in 2014 by order of the Science and Technology Vice-Presidency of Iran to manufacture national relay tester device under the supervision of Amirkabir University of Technology. AMT is a universal solution to testing all types of relays and protective equipment, circuit breakers, thermal cables and sensors as well as power, current, voltage and capacitor-voltage transformers. Because of these features, this device is capable of testing different kinds of relays and protective equipment:AMT105 Six 32A current sources (64A in three-phase mode, 128A in single-phase mode), four 150 V voltage sources (450 Vin single-phase mode), current and voltage combination cable, 8 analog binary inputs, 2 DC analog current and voltage inputs with high accuracy, 4 binary outputs, DC voltage source (212 V).AMT 205 Six 32A current (64A in three-phase mode, 128A in single-phase mode), In less than 300 milliseconds, there is a three-phase current of 70A and a single-phase current of 200A. six 300V voltage sources (1200V in single-phase mode), current and voltage combination cable, 8 analog binary inputs, 2 DC analog current and voltage inputs with high accuracy, 4 binary outputs, DC voltage Source (420 V).
Two important decisions were made in 2016, when Vebko started selling to more clients: First decision was to create Telegram group so that everyone can give feedback. Vebko has used these comments to improve the device, which led to adding more options. In January 2016, it was decided that any hardware problems must be reported on the website and Telegram group in a way that all users become aware of the problems and its solution. These two decisions helped Vebko to optimize the hardware and add software options. In October of 2015, the authorities in the Ministry of Petroleum were encouraged by contractors to use the device. In the beginning, because the tester has a high technology and there were certain concerns in this regard, the authorities in the Ministry of Petroleum were reluctant to use this device, but at the end of 2015, AMT105 showed a good performance compared with foreign devices. The authorities finally approved it in different phases of Asaluyeh, and the company was able to enter the Vendor List of Ministry of Petroleum in November 2015. In January of 2015, a decision was made so that AMT105 can be used for various applications, in addition to testing relays, such as key testing, CT test, transformer testing, and so forth. Then, the related functions have been added to the device.
