Ques:- How we calculate the current carriying capacity of the different sizes of Aluminium busbar ?
Right Answer:
The current carrying capacity of aluminum busbars can be calculated using the formula:
[ I = k times A times sqrt{T} ]
Where:
- ( I ) = Current (in Amperes)
- ( k ) = A constant based on the installation conditions (typically around 1.0 to 1.5)
- ( A ) = Cross-sectional area of the busbar (in square mm)
- ( T ) = Temperature rise (in degrees Celsius)
Additionally, factors such as ambient temperature, insulation type, and installation method should be considered. Standard tables and guidelines from organizations like the National Electrical Code (NEC) or the Institute of Electrical and Electronics Engineers (IEEE) can also provide specific current ratings for different sizes of aluminum busbars.

Ques:- How can you write a script without using GUI in QTP?
Asked In :-
uninterruptible power supplies ltd,
Right Answer:
You can write a script without using the GUI in QTP (QuickTest Professional) by using the keyword-driven or data-driven approach, or by directly editing the script in the VBScript editor. You can also create and run scripts using the QTP command line interface or by using a text editor to write the VBScript code and then executing it through QTP.

Ques:- How we can calculate the consumption in kwh of motor on basis of kw @100% load, @50% load & @ no load.
Asked In :-
Thales Group, uninterruptible power supplies ltd,
Right Answer:
To calculate the consumption in kWh of a motor based on its kW ratings at different loads, use the following formula:
1. **At 100% Load:**
[
text{Consumption (kWh)} = text{Power (kW)} times text{Time (hours)}
]
2. **At 50% Load:**
[
text{Consumption (kWh)} = left(frac{text{Power (kW)} times 50}{100}right) times text{Time (hours)}
]
3. **At No Load:**
[
text{Consumption (kWh)} = text{No Load Power (kW)} times text{Time (hours)}
]
Replace "Time (hours)" with the actual operating time to get the consumption in kWh for each load condition.

Ques:- How to isolate a DPT from line in the condition that processmust not be disturbed,and process is also critical and nobypass is available.?
Asked In :-
uninterruptible power supplies ltd,
Right Answer:
To isolate a Differential Pressure Transmitter (DPT) from the line without disturbing the process, you can use a "block and bleed" method. This involves:
1. **Block Valves**: Install two block valves (one upstream and one downstream) on the DPT's process connection.
2. **Bleed Valve**: Include a bleed valve between the two block valves.
3. **Isolation Procedure**:
- Close the downstream block valve.
- Close the upstream block valve.
- Open the bleed valve to relieve any pressure in the DPT, ensuring it is isolated from the process.
This method allows you to safely isolate the DPT while maintaining the integrity of the process.
