AMT is a universal solution for testing all types of relays and protection devices. AMT105 and AMT205 are two available units that can be used for secondary injection of relays.
T22 is a controllable single-phase current and voltage source with a rated output power of 5 kVA. This is designed and produced by ESFA Group which is suitable for performing various kinds of commissioning, periodic, and diagnostic tests.
T22 can be employed in high-voltage substations, distribution substations, power plants, industrial plants, equipment manufacturers, research centers, and universities. The output voltages can be controlled in the range of 0~2200 V-AC and 0~260 V-DC.
In addition, its output current can be controlled in the range of 0~1000 A-AC and 0~400 A-DC. Moreover, the frequency of AC voltage and
current is controllable between 15 and 120 Hz.
Furthermore, T22 can be synchronized with an external current or voltage source to generate either current or voltage with the same frequency, adjustable phase angle difference, and specified amplitude (up to 1000 A and 2200 V).
Applications of such a feature consist of amplifying an electrical signal, performing three-phase tests using three separate KAVOSH T22 devices, distance or
directional relay function test by the primary injection method, etc.
T22 has a built-in server to which every type of processing device with an internet browser can be connected (e.g., a laptop, PC, tablet, or cellphone). To do so, wireless communication (Wi-Fi) or direct connection by CAT 6 network cable can be utilized. Furthermore, a touchscreen LCD mounted on KAVOSH T22 can be used to perform all tests without using an external
The software quickly provides all the required reports and makes a database. Moreover, all the test results can optionally be sent to a server (ESFAnalysis software) by which they will be scrutinized based on standard guidelines, comparison to similar cases historical test results, and theoretical analysis.
