Grounding transformer for measuring instruments (current transformer CT, potential transformer PT) '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. For inquiries, please contact "lightstar_1979@yahoo.co.jp".
