WebCT ratio formula: CT ratio = I (P) / I (s) ————-1. Example: 1000:1. Here 1000 means it is a primary current and 1 means secondary current. Also, we can have rewritten as 1000/1. … WebApr 23, 2024 · Another way to view this calculation is that a 2000/5 CT is 20 x 2,000 = 40,000 Amps. This shows the CT will remain accurate in the field if there’s a 24,900A fault. To point out, the burden heavily impacts the CT accuracy rating. The lower the burden on the CT secondary, the higher the saturation point for a given CT.
Webmust consider the increased volt-time area of the asymmetrical fault when selecting a CT. Fig. 2. Burden Voltage for Asymmetrical Fault Current ... be used to calculate the maximum fault current for a given CT ratio. Table I lists the maximum fault currents versus X/R ratio for which saturation is avoided using 3000:5, 2000:5, or 1500:5 CTs. WebBy applying parallel CT, it is possible to increase CT accuracy voltage from 50V to 100V without reducing relay input current. Fig. 1.

WebThe CT Accuracy Class is listed on the label or the nameplate of the CT and is comprised of three parts: rated ratio accuracy rating, class rating, and maximum burden (Figure 2). Rated Ratio Accuracy Rating is a number which is the rated ratio expressed as a percent. For example, a CT with an accuracy class of 0.3 is certified by
