Johnson Controls Testing & Commissioning Engineer Interview Questions and Answers

TCS system stands for Turbine Control System, which is used in power plants to control and monitor the operation of turbines.

• TCS system is essential for ensuring the safe and efficient operation of turbines in power plants.

• It helps in controlling the speed, temperature, and other parameters of the turbine.

• TCS system also includes safety features to protect the turbine from damage.

• Examples of TCS systems include Woodwar

TCS (Temperature Control System) can be controlled using various methods such as PID controllers, PLCs, and SCADA systems.

• Use PID controllers to regulate temperature by adjusting the output based on the difference between the setpoint and actual temperature.

• Program PLCs to monitor and control temperature by receiving input from sensors and activating outputs to adjust heating or cooling devices.

• Implement SCADA systems ...read more

Scalance type selection is based on factors like network size, speed requirements, and redundancy needs.

• Consider the size of the network to determine the number of ports needed

• Evaluate the speed requirements to choose between Fast Ethernet or Gigabit Ethernet

• Assess the redundancy needs to decide on features like ring redundancy or port redundancy

• Examples: Scalance X-200 for small networks, Scalance X-400 for larger net

Load calculation in Engineering Design involves determining the amount of force or weight that a structure or component will need to support.

• Load calculation considers factors such as dead load, live load, wind load, seismic load, and temperature variations.

• Dead load refers to the weight of the structure itself and any permanent fixtures.

• Live load includes the weight of people, furniture, and other temporary items.

• Wind...read more

The challenge in designing and site activity is ensuring that the design is practical and can be successfully implemented on site.

• Ensuring that the design meets all technical requirements and specifications

• Coordinating with various teams involved in the project to ensure smooth execution

• Managing unexpected challenges that may arise during the erection and commissioning process

• Adapting the design if necessary to overcom...read more
