Question

Draw symbol of following: i) Earth Switch ii) Lightning arrester iii) Circuit breaker v) Isolator

Answer 1

Could you clarify if you need descriptions or representations of these symbols?

Answer 2

Sure! Here are the symbols for the components you requested:

1. **Earth Switch:**
   - The symbol for an earth switch usually looks like a switch symbol with a grounding symbol (a set of downward-pointing lines) attached. In simple terms, it's often depicted as a switch with an earth symbol or connected to a ground symbol.

2. **Lightning Arrester:**
   - The symbol for a lightning arrester is generally a vertical line with a zigzag or diagonal line through it, representing the path for lightning to follow. It can also look like a simple vertical line with a horizontal line through the top, often with a small grounding symbol below.

3. **Circuit Breaker:**
   - The symbol for a circuit breaker is typically a rectangle or a square with a line inside it that can be broken or opened. Sometimes, it’s depicted with two small arcs or a small circle indicating the breaking mechanism.

4. **Isolator:**
   - The symbol for an isolator is often a simple switch symbol with an indication that it is in the "off" position. It can also look like a switch symbol with an open gap in the line, indicating isolation.

Here are simplified representations:

1. **Earth Switch:**
   ```

   ```

2. **Lightning Arrester:**
   ```
      |
     /|\
     / \
    |___|

    |___|
   ```

3. **Circuit Breaker:**
   ```
     ______
    |      |
    |  -   |
    |______|
   ```

4. **Isolator:**
   ```
     ______
    |      |
    |  O   |
    |______|
   ```

These are basic representations; the exact symbols can vary slightly depending on the standards used (e.g., ANSI, IEC).
