Iec ratio

WebIEC ratio method. The IEC ratio method takes into account the same ratios as RRM and the faults are classified into nine categories. The same codes of the three ratios in Table 4 are used in Table 6 which presents code combination according to the IRM faults diagnostics. TABLE 6. WebThese current transformers are designed to meet the requirement of ANSI IEEE C57.13 standard or IEC 60044 standard. CTs are typically used for metering and relaying applications such as switchgear, MCCs, switchboards, etc. Single ratio or multi ratio models are available with various secondary termination options (leads, terminals etc.).
