Question:

The input current to a CO-8 relay is \(10 \mathrm{~A}\). Determine the relay operating time for the following current tap settings (TS) and time dial settings (TDS):

(a) \(\mathrm{TS}=1.0, \mathrm{TDS}=1 / 2\);

(b) \(\mathrm{TS}=2.0, \mathrm{TDS}=1.5\);

(c) \(\mathrm{TS}=2.0\), \(\mathrm{TDS}=7\);

(d) \(\mathrm{TS}=3.0, \mathrm{TDS}=7\); and

(e) \(\mathrm{TS}=12.0\), \(\mathrm{TDS}=1\).
