RISH Xmer measuring transformers manufactured by the Indian company Rishabh are included in the State Register of Measuring Instruments of the Russian Federation under number 94773-25 and are approved for various applications, including commercial utility metering.
The range of RISH Xmer transformers includes models with a primary current from 1 to 7500 A, an accuracy class from 0.2S and a busbar size of up to 165 mm. Low-current transformers have a built-in primary winding. Rishabh transformers can be used in systems of commercial and technical electricity metering, measurement and monitoring of switchgear parameters, protection and automatic control of electrical installations. The special design of transformers with a split core allows them to be connected without disassembling buses and cables, which significantly speeds up the installation process in existing electrical installations. Of interest are also compact three-phase models designed for installation together with the main switch, significantly saving space in switchboards.
The RISH Xmer model range consists of:
- Instrument transformers for mounting on a busbar or cable for currents from 30 to 7500 A.
- Instrument transformers with a primary winding for currents from 1 to 60 A.
- Protective transformers for currents from 100 to 6000 A.
- Split transformers for currents from 100 to 5000 A.
- Three-phase transformers for currents from 100 to 800 A.
