Yesterday, my brother came to me and asked if I could fix the AC window unit (which is the only AC we have in the house and it resides in his room) and I figured I would take a look.

The low voltage control circuits would power on, but the compressor and fan motor wouldn't and the temp sensor claimed a temperature of 49 degrees, when it very much was a muggy 80.

I took the covers off, looking for the temp sensor, but what I discovered was far more dramatic than a thermistor at the end of its life: three wires had burnt up. One spade terminal on the massive 35uF capacitor was blackened and another terminated to the end of a wire was practically melted. I measured the capacitance of the capacitors and they were fine. I had two theories for why this explosive event happened. The first was an over-current event caused by a short in the motor or compressor. The other was short caused by severe humidity or liquid water. There was a lot of water in the unit.

The motor spun just fine, so it wasn't seized. I figured I would cut and re-terminate the wires, connect everything, and try switching it on. And it worked! Some crimping, stripping, and soldering later, helped by a handy wiring diagram located inside the unit, and it ran. I jumped and laughed. My niece and nephew were hanging around with me in the garage, and they remarked that they hadn't heard me laugh in a long time, if at all.

I thought about this today and it was making me cry a bit. It had been so long since I had to solve a problem and fix it, physically. I need that in my life; it's my calling, and I've been deprived of it because no one will hire me for repair positions.

I went back to the college that brought me to this city in the first place and sat down with an advisor. I'm enrolling in the HVAC program and I begin in Autumn. Upon graduation, I become part of the HVAC union and they will get me a job. The mean rate is $27/hr.

I'm going to fix things again. I'm going to feel like a real person. The darkness that shrouded me during the pandemic will finally dissipate.

Magnetic resonance imaging (MRI) has become a very common and reliable way of diagnosing patients. Due to advance in technology and detailed information about the diagnosis in question, many people have relied on this procedure for the detailed and quality images. However it has not been without challenges and some of the challenges are the burns that result from these procedures. RF burn is damage caused to the skin or other tissues and they are mostly caused by ionizing radiation or exposure to energy from radio frequency. During medical imaging high exposure to X rays can result to these burns. Body cells are damaged by ionizing radiation when they interact as this result to damage. The body reacts to this and what results is an erythema (Diaz, et.al, 2010 pp 413). This is redness around the affected area. In most cases radio burns are associated to cancer because of the ability of ionizing radiation to cause damage to DNA thus making the cell cancerous. Radio frequency burns can be of first, second or third degree. Some of the burns are usually treated by plastic surgery. Causes Magnetic resonance imaging (MRI) is considered a safe diagnostic procedure. However excessive heating can result to injuries to the person who is undergoing the MR procedures. Some of the causes of these burns include: physiologic monitors, objects that are made from conductive materials, damaged coils and electronically activated devices. Heating of implants can sometimes be problematic if the devices are made from conductive materials whose shape is elongated or those that form loops with a certain diameter (ECRI Institute, 2008 pp 379). Excess MRI heating has been witnessed for particular types of catheters that have thermistors, guide wires, leads and also certain cervical fixation devices. The degree and nature of the health effects that result from overexposure to radio frequency is dependent on the intensity, frequency and exposure duration. Read the full article

Surge Protection Devices: Safeguarding Your Electronics and Electrical Systems

In today’s modern world, electrical devices and systems have become an essential part of daily life. From computers and smartphones to home appliances and industrial equipment, most of our devices are vulnerable to power surges. Power surges can occur for a variety of reasons, including lightning strikes, faulty wiring, or even the switching on and off of large appliances. Surge protection devices (SPDs) are the unsung heroes that protect these valuable assets. In this article, we’ll explore what surge protection device are, how they work, and why they are crucial for your home or business.

What is a Surge Protection Device?

A surge protection device (SPD) is a tool designed to prevent damage to electrical equipment caused by voltage spikes. These devices are used to protect appliances, electronic devices, and other electrical systems from transient overvoltages—surges that last only a fraction of a second but can cause significant damage to sensitive components.

Surges are typically brief bursts of electricity that exceed the normal voltage levels in a circuit. These overvoltages can be caused by a variety of factors, such as:

Lightning strikes: A direct or nearby lightning strike can introduce a massive voltage spike into the electrical system.

Utility power fluctuations: The grid can experience surges due to high demand, faulty transformers, or equipment failures.

Switching operations: Large machinery and HVAC systems turning on and off can cause brief surges in the system.

Surge protection devices help to divert or absorb these excessive voltages, preventing them from reaching and damaging connected equipment.

How Surge Protection Devices Work

SPDs are typically installed in power strips, wall outlets, or integrated into the electrical panel of a building. The core function of an SPD is to divert the excess voltage to the ground, preventing it from flowing through the device or circuit it’s protecting. There are several key components in an SPD:

Metal Oxide Varistors (MOVs): These are the most common components in surge protectors. MOVs have the ability to absorb and redirect excess voltage to the ground when a surge occurs.

Gas Discharge Tubes (GDTs): Often used in high-voltage applications, GDTs work by ionizing gas within a tube when a surge occurs, allowing the excess current to pass through and be safely discharged.

Thermistors: These resistors change resistance based on temperature. In the event of a surge, the thermistor’s resistance increases, limiting the flow of excess voltage.

Capacitors: Some SPDs include capacitors to filter out high-frequency electrical noise or spikes, providing additional protection against smaller, quicker surges.

The surge protection device works by identifying when a voltage surge occurs and either redirecting or absorbing the excess current. Once the surge subsides, the SPD resets itself, ready to protect again.

Types of Surge Protection Devices

Power Strips with Surge Protection: These are the most common type of surge protection used by homeowners. They provide multiple outlets and typically include an LED indicator to show that the device is still functioning. Power strip surge protectors are ideal for small electronics like computers, TVs, and game consoles.

Whole-House Surge Protectors: These are hardwired into the main electrical panel of a home or business, offering protection for the entire electrical system. They prevent surges from entering the building from external sources, such as lightning strikes or utility fluctuations, and can protect appliances, lighting, and sensitive electronics throughout the property.

Point-of-Use Surge Protectors: These are individual surge protectors placed directly at the power source of an appliance or electronic device. They are commonly used for expensive or sensitive equipment like servers, medical devices, and home theaters.

Industrial Surge Protectors: These are designed for heavy-duty applications in factories, manufacturing facilities, and large commercial buildings. Industrial SPDs can handle much higher voltages and are built to withstand more frequent or intense surges.

Why You Need Surge Protection Devices

The importance of surge protection cannot be overstated, especially given how much we rely on electronic devices. Here are some of the key reasons why surge protectors are essential:

Protects Expensive Electronics: Many modern electronics are highly sensitive to voltage fluctuations. A power surge can fry delicate circuits in devices like computers, televisions, audio equipment, and smart home devices. The cost of repairing or replacing damaged equipment can be significant.

Prevents Fire Hazards: A sudden surge in power can cause wires or electrical components to overheat, which could lead to a fire. Surge protection devices help to prevent this risk by redirecting or dissipating the excess voltage.

Extends the Lifespan of Equipment: Even if a surge doesn’t cause immediate damage, repeated exposure to minor voltage fluctuations can degrade components over time, leading to premature failure. Surge protectors help to ensure that your equipment lasts longer.

Minimizes Downtime: For businesses, electrical surges can cause downtime that disrupts operations and leads to financial loss. Surge protectors help to minimize this risk, ensuring that operations continue smoothly even in the face of power fluctuations.

Peace of Mind: Knowing that your electrical system is protected from surges provides peace of mind, especially when it comes to expensive or critical equipment.

Choosing the Right Surge Protection Device

When selecting a surge protector, there are a few factors to consider:

Joule Rating: This is the amount of energy a surge protector can absorb before it stops functioning. The higher the joule rating, the more protection it offers. For sensitive or expensive devices, a higher joule rating is recommended.

Clamping Voltage: This refers to the voltage level at which the surge protector will activate. A lower clamping voltage means the device will begin to protect against surges sooner.

Response Time: A surge protector with a faster response time can protect against quicker surges, reducing the risk of damage to your equipment.

Warranty and Protection Coverage: Many surge protectors come with a warranty that guarantees protection for connected devices. Be sure to check the warranty details when purchasing a surge protector.

Conclusion

Surge protection devices are crucial for safeguarding your electronics, appliances, and electrical systems from the risks of power surges. By diverting or absorbing excessive voltage, SPDs prevent damage to your valuable devices, reduce the risk of electrical fires, and extend the lifespan of your equipment. Whether you need a small power strip or a whole-house surge protector, investing in surge protection is a smart and cost-effective way to protect your home or business from the unpredictable nature of electrical surges.

What Is The Purpose Of Thermal Protector For Motor?

In the world of electrical engineering and motor technology, ensuring the longevity and safe operation of motors is paramount. One critical component in achieving this is the thermal protector. This device is designed to safeguard motors from the damaging effects of overheating, which can lead to motor failure, safety hazards, and costly downtime. In this article, we will explore the purpose of thermal protectors for motors, how they work, and the benefits they provide.

Overheating Protection

The primary function of a thermal protector is to prevent motors from overheating. Motors generate heat during operation, and under certain conditions—such as heavy loads, high ambient temperatures, or inadequate ventilation—the temperature can rise to dangerous levels. A thermal protector monitors the motor's temperature and disconnects the power supply if the temperature exceeds a pre-set threshold. This automatic shutdown prevents the motor's windings and insulation from being damaged by excessive heat.

Prolonging Motor Life

By preventing overheating, thermal protectors play a crucial role in extending the lifespan of motors.
