For this reason real estate investors in Rivers Edge Chicago will tell you that if you’re looking for a excellent MEP Engineering firm in Rivers Edge Chicago, IL you need to consider New York Engineers.

A mechanical, electrical, plumbing engineer, or MEP engineer, might be a huge asset. These engineers can manage a wide array of tasks. What exactly do MEP engineers do? Read on if you’d like to learn more about the duties which they carry out.

They Plan and Design Systems: A building must have a properly planned electrical system, and a building’s water system needs to be designed by a pro as well. The kind of engineer that is in charge of this design is undoubtedly an MEP engineer. Arranging these types of systems is very complex, which is why MEP engineers take extensive training. The work they do is not simple at all. With that in mind, structures with proper electrical and plumbing systems are less susceptible to problems than structures with carelessly designed systems.

They Develop Standards and Policies: In addition to crafting the systems for a building, it’s the task of MEP experts to build up the policies and standards for the building. An MEP expert will continue to work to make standards that are appropriate for a building. They may adjust or improve the benchmarks for any building when needed.

They Think Of Evaluation Tools: In order to ensure a method is operating as envisioned, a variety of assessment tools will need to be developed. Somebody who works as an MEP engineer could have to come up with the correct evaluation tools. If you have a challenge with the system, that issue will probably be diagnosed and settled straight away.

Precisely what do MEP engineers do? As you have read, these pros manage a variety of significant tasks. If you spend some time to read more about the tasks these particular pros manage, you will have the capacity to determine regardless of whether an engineer like this may be an asset to your company.

Why You Needed MEP Engineers in Rivers Edge Chicago if Planning Large Scale Construction Projects

It is likely you do not think that you need MEP engineering mentors, but you may have another idea about on the problem when you see what I have to say. The following is why someone would need MEP engineers if they were to start a huge construction project. I’m not just going to give you a few reasons; I will give you several of them.

Building designs throughout Kennedy Park Chicago, ILO, are usually complex, and you have to contemplate electrical, plumbing fixtures and HVAC system designs. Should I say more? Well, I did claim that I was going to provide you one or two reasons. There is more than the obvious if designing a building and these two primary examples is the best way to lead things off.

One reason why one needs MEP engineers when accepting a big construction project also is related to electricity and lighting. This is also a great time to bring up that energy maintenance is another reason. A thorough policy for energy maintenance includes the whole building and the way it is outfitted.

Fire alarms and security are one more primary reason to hire MEP engineers. You will desire them to assist you design an agenda for that fire security alarms and escape routes. Safety and security are addressed in lots of other methods in relation to the appearance of a building, as well.

MEP engineers in Homan Square Chicago, ILO, are willing to not merely help you in the design of a building but take over with all the knowledge and expertise needed to lead this kind of project. Building automation, operational maintenance and value in overall design are simply a few other reasons why you may want to put MEP engineers in the helm with regards to the larger scale construction project you may have planned. If you would like more info on the MEP Engineering services in Rivers Edge Chicago, IL by NY-Engineers.Com you should stop by at our Building Commissioning blog.

Electrical Safety and Power Quality: A Short Guide for Electrical Engineering

Electricity is one of the cornerstones of modern society, but it can be very dangerous if handled incorrectly. Therefore, governments have introduced stringent codes to regulate its use and ensure safety for occupants. A building’s power supply must be safe to use, and it must also have the voltage and frequency required by the electrical appliances in the building. The electrical engineering systems that provide electrical safety and power quality are typically hidden from sight, but they play a fundamental role in buildings.

Electrical issues are more common in pre-war apartment buildings and other old constructions. Always make sure you get the installation checked before moving into an existing property, but especially if it very aged.

Electrical Protection Devices

The main function of electrical protections is to disconnect the power supply when dangerous operating conditions are present. The main types of electrical faults found in electrical engineering systems are the following:

  • Overload or overcurrent
  • Short circuit
  • Ground fault
  • Line-to-line fault
  • Transient or voltage surge

Plug-in circuit breakers are perhaps the best-known electrical protection devices, commonly used in residential and light commercial applications (below 100 Amperes). Molded-case circuit breakers are generally larger and reach higher current ratings, while motor circuit protectors and thermal overload relays are designed for the protection needs of electric motors. Other than the plug-in configuration, there are protection devices designed for a DIN rail mount or for bolted connections.

An overload occurs when an electrical circuit is drawing current above its rated value for an excessively long period. It is important to note that short-duration overcurrent is common in some types of equipment. For example, three-phase electric motors may draw up to eight times their rated current during startup, but only for a short time – typically fractions of a second. Some types of lighting also draw an inrush current, especially if they have ballasts.

Circuit breakers typically use a thermal interruption mechanism to protect circuits from overload while allowing short-duration current peaks. The thermal protection mechanism uses a metallic contact that expands when heated by current, and it is calibrated to allow the circuit breaker’s rated current but not higher values. However, since inrush currents occur too quickly, their heating effect is not enough to expand and disconnect the thermal protection mechanism. On the other hand, an overload eventually trips the breaker; as current magnitude increases, the thermal protection contact expands faster and disconnects the circuit in less time.

A short circuit occurs when a live conductor touches a neutral conductor, causing a very high current. The magnitude of a short circuit fault is very high, typically thousands of amperes, so it must be disconnected as quickly as possible. In this case the response of thermal protection is too slow, so the protection mechanisms that clear short circuit faults are based on electromagnetic induction – the intense current induces a strong magnetic field that disconnects the circuit breaker.

A ground fault, also known as a line-to-ground fault, occurs when a live conductor touches a conductive element that is not part of the electric circuit. This also creates a very high current due to the low contact resistance, activating the magnetic protection mechanism of the respective circuit breaker. A line-to-line fault occurs when two live conductors at different voltage touch each other, also causing a high-magnitude current. In both cases, the same magnetic protection mechanism that clears short circuit faults responds and trips the circuit breaker.

All the faults described above are characterized by excessive current. When a high voltage peak occurs, the fault is called a transient or a voltage surge. Voltage surges normally occur when large equipment is switched, and can also be caused by lightning. Since circuit breakers are not designed to protect installations from voltage surges, you must use a surge protection devices (SPD) or transient voltage surge suppressor (TVSS). One of the most common types of TVSS use a variable resistance (varistor) connected between the live conductors and the ground – its resistance is high under normal operating conditions, but drops to a very low value in response to voltage peaks, discharging the fault to the ground before it reaches sensitive equipment.

Improving Power Quality in Electrical Engineering Systems

Electric power systems may also suffer from issues that are not faults strictly speaking, but which are also detrimental for performance. Two of the main issues are low power factor and harmonics.

Power factor is a very abstract concept, but the following is a simple way to visualize it. Some types of electrical equipment draw current in such a way where not all the power drawn from the voltage supply is really consumed. In these cases, the term “real power” is used to describe the power that is actually used, and the term “reactive power” is used to describe the portion that oscillates back and forth between the equipment and the power supply without being used. Some of the most common loads associated with reactive power are electric motors, transformers and ballasts. The power factor is the ratio of the real power used and the apparent power – the direct multiplication product of voltage and current.

  • Assume a single-phase motor consumes 900 W of electric power while drawing 5 amperes at 240 volts.
  • The apparent power is 1,200 volt-amperes (240V x 5A).
  • The power factor is 0.75 (900W / 1200 VA). It can also be reported as 75%.
  • The maximum possible value is 1.00 or 100%, where all the power drawn from the voltage source is consumed. Purely resistive loads such as incandescent lamps and resistance heaters behave this way.

Low power factor increases the current drawn by a building, and this creates an extra burden for the grid. Therefore, utility companies typically penalize users that allow their power factor to drop below a specified value. Low power factor is corrected by installing capacitors, which are similar to batteries but designed for a much faster cycle – the oscillating current that characterizes reactive power is supplied locally by the capacitor, and not drawn from the power grid, sparing the user from extra charges.

Power factor correction is characterized by its quick payback period, typically less than one year.

Harmonics are voltage and current signals whose frequency is a multiple of the service frequency – 60 Hz in the USA. Harmonics are produced by nonlinear loads such as magnetic cores and digital equipment, and they tend to overheat circuits, especially the neutral conductor. Excessive harmonics can also cause some types of electronic equipment to malfunction. Harmonic filters are devices that are tuned for a specific harmonic frequency, and when installed in a power system they prevent the propagation of harmonics beyond the equipment that generates them.

Conclusion

The best recommendation to keep all these electrical issues under control is to seek professional assistance from an electrical engineering profession. In new constructions, protection and power quality can be addressed from the design stage. For existing buildings, power monitoring equipment can be used to detect harmonics or low power factor, and the measurement results are then used to specify harmonic filters and capacitors. If circuit breakers are tripping frequently, get an inspection to determine the cause: there could be an electrical fault, but the breaker itself could also be damaged.
