Company Profile

 Founded in 2000 and headquarter located in Chengdu, China, Tesient Instrument has engaged in R&D, manufacturing and sales activities for power system test equipments since then.In 2001, Tesient brought M2000 series relay test equipment to the market, which using the DSP and switching amplifier technologies, making it an easy control, big power and light-weighted relay test kit.Since 2003, Tesient developed ME2000, MC2000 serries relay test equipment, which were of local control with display, making them capable of self operation without external PCs.In 2004, Tesient developed MD2000 series 6-phases relay test equipment, and power amplifier for power system simulation.In 2008, Tesient developed MP3000 series 6-phase relay test equipment, by using Tesient’s high efficient linear amplifier technology and divided ranges, MP3000 can provide high accurate outputs with excellent signal quality. 
In 2009, Tesient developed MF3000 series digital relay testers for substations implementing IEC61850 standards.Since 2004, Tesient began to sale its products world wide. Till now, Tesient has sold more than 200 sets of relay test kits to more than 15 countries.
Recently, Tesient upgraded ME2000 and MC2000 to ME3000 and MC3000. The new versions keep the original version’s local control and display features, but use Tesient’s highefficient linear amplifier technology thus having higher accuracy and stable voltage and current outputs. These two products are low cost oriented, therefor can provide customers cheap and cost-effective products. Refer to individual product specifications for details.
