The backplane design enables the insertion or extraction of the module while the system is energized, provided that local safety procedures regarding CT\/VT circuit isolation are strictly followed.\u003c\/p\u003e\n\u003cp\u003eQ: Can the CT input ratings be modified via software?\u003c\/p\u003e\n\u003cp\u003eA: The physical CT input hardware is typically fixed to 1A or 5A ratings. While software configuration is used for scaling and primary-to-secondary ratio setting, ensure the hardware hardware jumpers or model selection matches the physical CT secondary rating to prevent measurement errors.\u003c\/p\u003e\n\u003ch3\u003eField Installation Guidelines\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Insert the module into the designated UR relay slot and secure the locking levers. Ensure the backplane connector is fully mated to maintain the high-integrity contact required for low-level CT and VT signal paths.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrounding:\u003c\/strong\u003e The UR chassis must be connected to the substation earth bus via a low-impedance ground strap. A solid ground connection is mandatory to prevent electromagnetic interference (EMI) from affecting the analog-to-digital conversion process.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWiring:\u003c\/strong\u003e Use shielded, twisted-pair cabling for all CT and VT inputs. Route these signal lines through dedicated conduit, ensuring a minimum separation of 150 mm from high-voltage AC lines to mitigate inductive noise coupling that can cause maloperation of protection elements.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"General Electric","offers":[{"title":"Default Title","offer_id":47981431128254,"sku":"UR6NA","price":100.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0725\/1145\/5422\/files\/screenshot_2026-07-06_10-09-43_ea981862-4caf-4812-afa9-da4551347db2.png?v=1783419205","url":"https:\/\/www.autooiltech.com\/products\/ge-ur6na-ct-vt-module","provider":"AutoOilTech Limited","version":"1.0","type":"link"}
