Its single-conductor guidance applies to ordinary load measurement; dedicated residual-current or summation schemes require their own design instructions.<\/p>\n<h3 class=\"wp-block-heading\">Define the measurement boundary<\/h3>\n<p class=\"wp-block-paragraph\">A CT at a grid connection, between an inverter and a distribution board, or on a load branch answers a different question. A correct arrow cannot compensate for a CT installed at the wrong system boundary. Record the target, physical location, monitored conductor, positive direction, voltage reference and monitoring mode.<\/p>\n<h3 class=\"wp-block-heading\">Read the documented polarity convention<\/h3>\n<p class=\"wp-block-paragraph\">CTs may use an arrow, P1\/P2, H1\/H2, K\/L, a dot or another mark. The meaning must come from the CT or meter documentation. Follow this order: identify the exact CT and receiving device; read the positive-flow definition; compare the mark; check the voltage-reference phase and input channel; then check ratio, scale and mode.<\/p>\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.se.com\/au\/en\/faqs\/FA203850\/\" target=\"_blank\" rel=\"noopener\">Schneider\u2019s CT orientation guidance<\/a> covers polarity marks and limits installation and maintenance to qualified personnel.
