Precede Systems Interview Questions and Answers

I manage number of calls/complaints by implementing proactive maintenance strategies, analyzing root causes, and improving communication channels.

• Implement proactive maintenance strategies to prevent issues before they occur

• Analyze root causes of calls/complaints to address underlying issues

• Improve communication channels with customers to address concerns effectively

An APFC panel works by automatically adjusting the power factor of electrical systems to improve efficiency and reduce energy costs.

• APFC panel measures the power factor of the electrical system

• It then automatically switches capacitors in or out of the circuit to adjust the power factor to a desired level

• This helps in reducing reactive power, improving efficiency, and lowering electricity bills

VFD stands for Variable Frequency Drive, used to control the speed of an AC motor by varying the frequency and voltage supplied to the motor.

• Controls the speed of AC motors by adjusting frequency and voltage

• Improves energy efficiency by matching motor speed to the required load

• Reduces wear and tear on motors by soft starting and stopping

• Commonly used in HVAC systems, pumps, and fans

RAC stands for Reliability, Availability, and Capability. It is a method used to assess the performance of a system.

• RAC is used to evaluate the reliability, availability, and capability of a system or process.

• Reliability refers to the probability that a system will perform its intended function without failure over a specified period of time.

• Availability measures the percentage of time that a system is operational and can be used when needed.

• Capability assesses the ability of...read more

Power factor is a measure of how effectively electrical power is being used in a system.

• Power factor is the ratio of real power (kW) to apparent power (kVA) in an electrical system.

• It indicates how efficiently power is being converted into useful work.

• A power factor of 1 indicates all power is being used effectively, while a lower power factor means some power is being wasted.

• Power factor correction is often used to improve efficiency and reduce energy costs.

MTBF stands for Mean Time Between Failures and MTTR stands for Mean Time To Repair.

• MTBF is the average time between failures of a system.

• MTTR is the average time taken to repair a failed system.

• MTBF + MTTR = Mean Time To Failure (MTTF)

• MTBF and MTTR are key metrics in reliability engineering to assess system performance.
