Protection System
A system that protects electrical systems from faults by isolating the problematic part from the remainder of the system, preventing power from being cut from healthy elements, improving system dependability and efficiency is the protection system. Protection devices are the equipment that are utilized to implement the protection system.
Predictive Maintenance System
Predictive maintenance technologies are designed to assist in determining the state of in-service equipment so that maintenance can be scheduled. Predictive maintenance is the application of information; proactive maintenance approaches examine the condition of equipment and anticipate when it should maintain. The purpose of predictive maintenance is to forecast when equipment will fail (depending on a variety of parameters), then prevent the failure through routine and corrective maintenance.Condition monitoring is the continual monitoring of machines during process conditions to maintain optimal machine use, which is necessary for predictive maintenance. There are three types of condition monitoring: online, periodic, and remote. Finally, remote condition monitoring allows the equipment observed from a small place and data supplied for analysis.
Preventive Maintenance System
To maintain the equipment and materials on a regular basis in order to maintain those running conditions and reduce unnecessary shutdowns due to unexpected equipment failure is called Preventive Maintenance (PM).

![### Series and Parallel Resistor Network Analysis
In the provided circuit diagram, we need to determine the equivalent resistances between points A and B, which are represented as \( R_{eq12} \) and \( R_{eq13} \).
#### Description:
- **Resistors in Series and Parallel:**
- Several resistors with resistances of 3kΩ are arranged in both series and parallel configurations.
- **Analyzing the Network:**
- The topmost path includes two resistors in series, both marked as 3kΩ.
- The bottommost path also contains two resistors in series, each 3kΩ.
- These two series paths create a parallel network:
- The central part of the network connects the two horizontal paths with three vertical 3kΩ resistors arranged in series.
- Additionally, there is a diagonal 3kΩ resistor linking the middle junction points of the vertical and horizontal resistors.
- This configuration needs to be simplified to find the overall equivalent resistance.
#### Approach to Simplification:
1. **Identify Parallel and Series Connections:**
- Combine series resistors first:
- The top two resistors add up to form \( 3kΩ + 3kΩ = 6kΩ \) in total.
- Similarly, the bottom two resistors also form \( 3kΩ + 3kΩ = 6kΩ \).
2. **Reduce the Combined Resistors in Parallel:**
- Calculate the equivalent resistance of the two series pairs in parallel:
- Formula for parallel resistors:
\[
\frac{1}{R_{equivalent}} = \frac{1}{R_1} + \frac{1}{R_2}
\]
- Applying for our pairs:
\[
\frac{1}{R_{parallel}} = \frac{1}{6kΩ} + \frac{1}{6kΩ}
\]
\[
R_{parallel} = 3kΩ
\]
3. **Considering Other Resistors in the Network:**
- The vertical 3kΩ resistors are positioned to form new series and parallel combinations that need further steps for consolidation.
- The diagonal resistor provides an additional path affecting the equivalent resistance.
#### Final Equivalent Resistance:
- The final equivalent resistance calculation may require iterative simplification steps considering both series and](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff920003c-b80d-4d46-9199-437e1336b936%2F6791471f-0c1b-4157-92fd-c04a6e2eed58%2Fi3lw3p7_processed.png&w=3840&q=75)

### Resistor Network Diagram
The image above illustrates a network of resistors arranged in both series and parallel combinations. The goal is to determine the equivalent resistance (\( R_{eq} \)) of the network as indicated by \( R_{eq11} \). Here are the details of the components and their connections:
1. **Resistors:**
- **2 kΩ Resistor**: Connected in series at the top left of the network.
- **4 kΩ Resistor**: Connected in series after the 2 kΩ resistor.
- **12 kΩ Resistor**: Placed in parallel with the combined network of the 4 kΩ, 3 kΩ, and 6 kΩ resistors.
- **3 kΩ Resistor**: In series with an intermediate node.
- **6 kΩ Resistor**: In parallel with the 3 kΩ resistor from the intermediate node.
2. **Connections:**
- The 4 kΩ and 3 kΩ resistors form a series combination.
- This series combination (4 kΩ + 3 kΩ) is in parallel with the 6 kΩ resistor.
- The 12 kΩ resistor is in parallel with the entire combination mentioned above.
- Finally, this combined parallel set-up is connected in series with the initial 2 kΩ resistor.
### Steps to Calculate Equivalent Resistance (\( R_{eq} \)):
1. **Series and Parallel Combinations**
- First, compute the equivalent resistance of the 3 kΩ and 6 kΩ resistors in parallel:
\[
R_{\text{parallel}} = \left(\frac{1}{3 kΩ} + \frac{1}{6 kΩ}\right)^{-1} = 2 kΩ
\]
- Next, add the 4 kΩ resistor in series with the above combination:
\[
R_{\text{series}} = 2 kΩ + 4 kΩ = 6 kΩ
\]
- Then, calculate the equivalent resistance of the 12 kΩ resistor in parallel with the 6 kΩ obtained above:
\[
R_{\text{parallel total}} = \left(\frac{1}{6 kΩ}](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff920003c-b80d-4d46-9199-437e1336b936%2F6791471f-0c1b-4157-92fd-c04a6e2eed58%2Fx79ypk6k_processed.png&w=3840&q=75)
