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

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