WebFeb 17, 2024 · For voltage transformers (PT) TCF at 0.6 power factor is defined as: Ratio Correction factor (RCF): The ratio of true ratio to the marked ratio. If a PT has a marked ratio of 480V/120V (ratio of 4), but the actual ratio is 480V/122V (ratio of 3.934), then RCF can be computed as 3.934/4 = 0.9836. WebThe excitation curve shown in Figure 4 represents a C400, 2000:5 multi-ratio bushing ct and is a measure of ct performance that can be used to determine ratio correction factors at various levels of steady-state excitation. Where it has a well-defined knee-point, it has no discernable point of saturation. software used to port weapons to waw
