4. Experience relay by connecting the coils in parallel repeat.

5. Relay vine sharp when it changes work checking see _ Of this for relay in the womb installation until suitable of the relay work current rheostat using fruit do it and head the contactor disconnect. Then the contactor connects of the relay work watch _ Current value by 5% when reduced of the relay that it doesn't work trust harvest come _
6. Relay the most small in the installation consumption who does power ammeter and voltmeter using define _
7. Relay to work drop off the time determination shown in Figure 2 for scheme collect _ Measurements Ir =2Ikuy and Ir = 31 tunes do it
8. RT-40 type relay immutable vine to the chain connect and his to work drop off until variable on the vine that it worked relatively how to change checking see _
9. Tension relay check shown in Figure 3 for scheme collect _ 10. Tension of the relay on the scale each installation for to work drop off voltage , return Voltage and Back to coefficients define _ Received present the results in Table 2 .
