Grounding transformer for measuring instruments (current transformer CT, potential transformer PT) 'KBG-□□□'
KBG-□□□
Indoor PT products that can convert voltage! Please use them first. Instruments for distribution boards, control panels, distribution panels, and panels.
KBG-□□□ is our indoor 1.15 kV transformer (PT). The primary voltage is 380/√3V or 440/√3V. It is used for zero-sequence voltage detection (tertiary) during faults in ungrounded lines. This product is a single-phase transformer, and three units are combined for use, with the connection method being Y connection for primary and secondary, and broken delta connection for tertiary. When the bus voltage is applied to the primary side, the secondary side is used for relaying and measurement, while the tertiary side can be used for zero-sequence voltage detection. On the tertiary side, zero-sequence voltage meters, OVGR (overvoltage ground relay), ground fault confirmation lamps, CLR, SGR, DGR, etc., can be connected for use.

Company information
Our company was founded in 1979 and has grown into a manufacturer of products that can observe electrical data through early analog instruments, digital meters, wireless, and the internet. This development is driven by the strong will of our employees to walk alongside our customers. Additionally, we are committed to thorough customer-centric operations while actively investing in technological development at our affiliated research institute. We strive to meet our customers' diverse needs through more differentiated services. In our case, we have become well-known in South Korea for our measuring instruments (analog, digital meters, and CT, VT). We have been exporting to Japanese companies for over a decade, and we have registered with Ipros to introduce our products to more Japanese customers. In 2022, we registered as a corporation in Tokyo and have since relocated our corporate office to Osaka as "LIGHTSTAR JAPAN." We also have Japanese staff on-site, and we look forward to your support.
