A reliable electrical power infrastructure is a significant advantage for Canadians, allowing you to routinely access electricity with ease. This stability, while convenient, can also lead to complacency, which can be disrupted by unexpected outages impacting not just comfort, but also safety and financial planning.
Within the realm of condo property management, power outages can have serious consequences. Loss of electricity may necessitate urgent health and safety measures, including potential evacuations, that disrupt daily life and incur additional costs. While individual actions have limited impact on maintaining the grid, reducing electricity consumption can decrease the overall strain and help prevent equipment issues and outages.
Basics of Electrical System Care
Keeping your electrical system in top condition is crucial for safety and consistent operation within a building. You play a key role in ensuring the system runs smoothly by planning regular maintenance. This includes gaining an awareness of how electricity is delivered to and distributed inside your facility. Prioritize this knowledge as part of your maintenance strategy.
Main Transformer
Electricity is delivered to buildings at high voltages to keep costs down and increase efficiency, often reaching 25,000V or more. Before this power can be used safely, it needs to be transformed to lower, more manageable voltages. Transformers perform this crucial function, reducing high voltages to usable levels found in homes and businesses. You may not realize it, but transformers are ubiquitous, even present in the form of the charging adapter for your phone.
Newer construction benefits from receiving power at around 600V, which is ideal for energy-intensive equipment like chillers or elevators. This voltage, however, still poses significant safety risks. Common building systems typically operate at 120/208V or 240V. For residential use, the voltage is commonly adjusted to 120/240V or 208V to meet everyday needs.
In most buildings, the primary transformer is either installed in a vault below ground or positioned outside on a concrete pad. Utilities usually own and manage these transformers, meaning you might not have direct access if they're housed in a vault. Yet, responsibility shifts if the vault is on your property; maintaining the vault's condition becomes your obligation. Structural issues or water intrusion could damage the transformers, potentially leading to power outages or fires.
Annual inspections are recommended to prevent such scenarios. During inspections, check for signs of water leakage, structural damage, flooding, overheating, or pest infestations. These issues must be addressed promptly to ensure the transformer remains in good condition.
For transformers set on external concrete pads, the situation differs slightly. Here, ownership of the pad and cables often lies with you. Regularly inspect the pad for any settling or wear, as significant movement could strain cable connections, resulting in power failure, electrical arcing, or fire hazards.
A trend in new condominium developments is the housing and ownership of the main transformer and high-voltage switchgear within the building. This setup often translates into favorable energy rates, as utilities may offer discounted hydro rates for such configurations. Nonetheless, with ownership comes the need for vigilance and proactive maintenance to safeguard your electrical systems and ensure uninterrupted power delivery.
Primary Distribution
Power from the main transformer flows into the primary switchgear, akin to a main breaker panel in residential settings. This switchgear consists of metal cabinets with integrated power bars for managing electricity distribution throughout a building. It segments the primary electrical supply into manageable portions for various uses. Safety features like fuses or breakers are incorporated to prevent electrical faults or overloading.
For a condominium, the primary switchgear may include switches dedicated to suite power risers, essential mechanical systems, elevator operations, generators, lighting arrays, and motor starter centers. If operating at 600V, secondary transformers are employed to lower the voltage to 120/208V. This reduced voltage is suitable for general application, powering lights, outlets, and other standard electrical devices. Substations such as main electrical rooms or service areas, including the elevator machine room and mechanical penthouse, house these transformers to facilitate efficient energy distribution.
Electricity intended for communal areas, often referred to as "house" loads, is routed from the primary switchgear to distribution units like splitter boxes, disconnects, and panelboards. These units contain circuit breakers or fuses managing specific applications such as lighting, power receptacles, electric water heaters, and more.
In the context of a condominium tower, power from the switchgear is typically divided among vertical risers. These risers ensure efficient power distribution to various floors through stacked electrical closets, each equipped with a main panelboard containing breakers for individual suites.
Maintenance of Electrical Systems
To ensure reliable functioning of your electrical systems, it's important to conduct regular check-ups and schedule professional interventions either yearly or every two years. Key maintenance tasks involve frequent inspections by your team and professional assessments periodically.
Visual Examination
You should perform regular visual examinations of electrical areas, ideally every month, to ensure everything is in proper order. One of your first priorities is to guarantee that the area is securely locked with a tamper-proof mechanism. When inspecting, maintain a safe distance and refrain from touching anything.
It is essential to keep a one-meter clearance in front of distribution gear and avoid storing items in these areas, especially on top of transformers. Check for leaks or damage, and if you notice any, place drip pans beneath pipes and drains to prevent liquid from contacting live equipment.
Look for any signs of deterioration like rust, water stains, scorch marks, overheating, dust, or dirt on the equipment. Confirm that the room's temperature is moderate and that any exhaust fans are functioning. You can typically test the fan using a wall switch or thermostat.
Make sure all electrical panel covers are intact, correctly installed, and without gaps, which could become hazards. Ensuring these precautions can help in maintaining a safe and efficient electrical room.
Thermal Imaging
Electrical systems typically operate with some warmth, but excessive heat is a sign of trouble. Utilizing thermal imaging to scan switchgears and panelboards helps identify these areas of concern. Conducting these assessments regularly can prevent potential damage or fire by allowing early diagnosis and timely repairs.
An annual check is generally justified due to its cost-effectiveness. For buildings less than two decades old, every two to three years may suffice, helping you ensure that your infrastructure remains safe and efficient without unnecessary expense.
Maintaining Switchgear
Regular inspection and upkeep of switchgear in large buildings are crucial. You should visually inspect the equipment for signs of issues, test the trip settings, and exercise and lubricate the switches. Cleaning the interior components and tightening connections to the manufacturer's specifications is essential. Thermal scans also play a vital role in this maintenance. Site history, age of the equipment, and risk tolerance of ownership will influence how often maintenance is performed. Newer installations might only need servicing every three to five years, while older equipment, particularly those over 20 years old, may require more frequent annual attention.
Arc-Flash Analysis
Uncontrolled electricity can travel through the air and lead to damaging incidents like arcing. This can result in shocks and fires. If you're working on or near live electrical apparatus, especially those with high voltages, you're at heightened risk for arc-flashes.
To mitigate these risks, the Canadian Standards Association (CSA) introduced the CSA Z462 Workplace Electrical Safety Standard. This standard aligns with NFPA 70E and provides essential guidance for evaluating electrical dangers and designing safe work environments around power systems.
Conducting an arc flash analysis helps categorize equipment based on risk levels, allowing you to select the proper safety gear. Regular reviews every five years or following major system changes are crucial. Although not obligatory for residential complexes, understanding and documenting the arc flash risks can enhance safety for both workers and organizations.
Reserve Funds
Allocating resources appropriately in a reserve fund is critical to ensure financial preparedness for replacing electrical equipment. Electrical assets have varying lifespans; major components like transformers and switchgear often need replacement every 35 to 45 years, while smaller parts such as panelboards may last only 15 to 25 years. You should consider comprehensive planning to handle these expenses, which includes earmarking funds for large-scale replacements. Projects such as main transformer replacements should be proactively planned, allowing you to secure temporary power supplies and obtain competitive bids through careful specification and tendering. This approach not only saves money but also minimizes disruptions caused by unexpected equipment failures, where costs and inconvenience can quickly escalate.
Develop a Strategy
Creating a thorough maintenance strategy with your electrical expert is crucial. This ensures the condominium's power system functions safely and efficiently, extending its operational life. With careful planning, you significantly minimize the chance of unexpected failures, which can cause major disruptions or hazards. Collaborate closely to keep systems in top shape.
