How to Protect Your Inventory With a Preventative Maintenance Program

Utility companies depend on a well-stocked inventory of parts to keep operations running smoothly. However, the presence of low-quality components in these inventories can lead to serious disruptions, from unexpected equipment failures to extended downtime. Addressing these risks has become a top priority for many affected industries, and a preventative maintenance program offers a practical solution to keep operations efficient and safe.

In this blog, we’ll explore how such a program can help utilities protect their inventory from low-quality parts. We’ll also touch on the role of electrical component testing, testing services, and accredited calibration in verifying the quality and reliability of parts before they are used in critical applications.

Faulty parts can have serious consequences for utility operations. When critical components like transformers, breakers, or connectors fail, the issues extend beyond simple repairs and can lead to:

• Extended downtime, causing delays in service restoration.
• Increased maintenance costs due to repeated failures.
• Safety hazards that may endanger workers and the public.

Certain parts, especially those used in critical environments, are important to monitor, particularly those prone to failure. Without a reliable preventative maintenance program, these components may go unnoticed, leading to the following:

• Operational delays that could have been avoided.
• Unexpected failures that disrupt efficiency and safety.

These issues are particularly important in high-demand regions with rapidly growing infrastructure, such as North Carolina and Texas, where downtime can lead to significant operational delays. Key steps to reduce these risks include:

• Utilizing electrical component testing to identify potential issues early.
• Partnering with an electrical or mechanical testing laboratory to conduct thorough reliability evaluations.
• Implementing critical component testing services to make sure parts are fit for high-demand applications.

These measures help utilities maintain the quality and reliability of their inventory, minimizing the chances of malfunction.

A well-structured preventative maintenance program is important for avoiding operational disruptions caused by faulty components. By proactively identifying and addressing low-quality parts before they reach the field, utility companies can maintain smooth operations and reduce the risk of unexpected failures.

Key benefits of implementing a preventative maintenance program include:

• Early detection of defective components, preventing them from being installed in critical systems.
• Thorough testing of essential parts, such as transformers and breakers, to make sure they meet performance standards.
• Reduced downtime, as faulty parts are identified before they cause major operational delays.

Reliability in utility operations is measured through critical indices that track the frequency and duration of interruptions. A preventative maintenance program plays a crucial role in improving these indices:

• System Average Interruption Duration Index (SAIDI) measures the total duration of interruptions experienced by the average customer. By removing defective components before they cause issues, preventative maintenance helps minimize the duration of service disruptions, supporting lower SAIDI scores.
• System Average Interruption Frequency Index (SAIFI) calculates the average number of interruptions a customer would experience. A maintenance program that rigorously tests and verifies part quality reduces the likelihood of equipment failures, thus improving SAIFI by lowering interruption frequency.
• Customer Average Interruption Duration Index (CAIDI) reflects the average time required to restore service after an interruption. With proactive maintenance, utility companies can respond faster to interruptions, reducing CAIDI scores and ensuring quicker service restoration.

An important aspect of a preventative maintenance program involves partnering with an accredited laboratory that not only performs calibrations but also offers advanced testing services.

Using predictive maintenance data from decades of failure rate trends on critical components, a testing laboratory can help identify potential issues ahead of time, ideally during the procurement phase or for parts in inventory. These specialized tests assess the quality and durability of electrical or mechanical components, making sure they perform their critical functions and are fit for real-world applications.

By integrating rigorous testing and inspections within the preventative maintenance program, utility companies can:

• Verify the reliability of mechanical and electrical parts and prevent costly failures.
• Mitigate risks by ensuring all components pass strict testing protocols.
• Protect their operations from the hidden costs of using low-quality parts.

Having a strong program in place is key to preventing disruptions caused by faulty parts. By partnering with a trusted testing company, you can stay ahead of potential issues and maintain the quality of your inventory. Implementing a preventative maintenance program helps safeguard your operations, keeping everything running smoothly and efficiently.

A preventative maintenance program becomes even more effective when paired with a Parts Quality Initiative (PQI). This initiative focuses on identifying high-risk parts to help utility companies avoid unreliable components before they even enter their inventory. A subscription-based PQI tracks manufacturer and model performance, allowing companies to spot patterns in failure rates.

Key benefits of incorporating PQI include:

• Identification of high-risk parts based on manufacturer and model performance, supporting lower SAIDI by reducing the risk of prolonged outages.
• Smarter procurement decisions that reduce failures and downtime, which can directly improve SAIFI by minimizing the number of interruptions caused by faulty components.
• An opportunity to clear out old parts and determine what should be sent for testing of critical components, making sure they meet reliability standards that contribute to a consistent CAIDI.
• Improved insight into which parts require more rigorous testing through services like calibration services or from a testing laboratory.
• Data-driven decisions that improve overall inventory management.

By sending critical parts for testing, especially those under warranty, utilities can prevent costly failures and increase operational reliability.

A preventative maintenance program doesn’t just stop at detecting faulty parts; it also plays a critical role in testing and verifying parts still under warranty. By identifying issues early, utility companies can return defective parts to manufacturers at no additional cost. This process makes sure that parts meet quality standards and operate as expected, reducing the risk of failure during critical operations.

Key steps in the testing and verification process include:

• Sending critical components in for thorough testing and evaluation to confirm their performance under real-world conditions.
• Utilizing accredited laboratories that offer comprehensive testing and calibration services for accurate results.
• Leveraging PQI data to determine which parts need more rigorous evaluations to maintain operational reliability.

Working with an accredited electrical testing company can provide the necessary expertise to handle these processes efficiently, making sure that all parts, especially those still under warranty, meet the highest performance standards.

Adopting a preventative maintenance program along with smarter procurement practices can help utility companies avoid costly downtime and improve operational reliability. By using services like electrical component testing and calibration, industries across the world can make sure their inventory is equipped with reliable, high-quality parts.
