20. PROTECTION SYSTEM REQUIREMENTS
To get a good protection system required several conditions, among others:
Ability in detecting the minimum disturbance to the stimulus and only decided that the system is interrupted only.
1. Sensitive:
A quality of neatness in the election security.
2. Selective:

21. PROTECTION SYSTEM REQUIREMENTS
To get a good protection system required several conditions, among others:
Reaction from the protection system when the disturbance must occur quickly to minimize the objective possibility of expansion due to the disruption caused.
3. Fast:
Ability protection system in normal circumstances and in the interference and should certainly work. So that the reliability of equipment protection system terga, the required periodic testing.
4. Reliable :

22. PROTECTION SYSTEM REQUIREMENTS
To get a good protection system required several conditions, among others:
With the cost of a child-protection system is expected to be able to work well
5.Economical:
System protection devices have required a simple and flexible.
6. Simple:

23. Standard protection system requirements:
STANDARD TERMS OF PROTECTION SYSTEM
Standard protection system requirements:
1. Protection system must be able to nominal flow continuously without excessive heating (overheating).
2. Overload on a small lapse of time that short should not cause the equipment to work.
3. Protection must be working, even though the overload occurs a small but long enough so that they can cause overheating in the series conveyor.

24. Standard protection system requirements:
STANDARD TERMS OF PROTECTION SYSTEM
Standard protection system requirements:
4. Protection must be opened before a series of damage caused by the flow disturbances that can occur;
5. Protection must be able to "separation" (discriminative) only on the set of the series only and subject to the other should still operate.
