There are several different types of medium voltage earthing systems. These systems can be differentiated by using the neutral point connection method. They are different in the way that they operate and each of them has its own pros and cons. These earthing systems in medium voltage include the likes of:

The functioning of each differs from the other. They also have various applications. Let’s have a look at each system at a time:

In this one, there is no electrical connection between the earth and the neutral point except for the devices that are used for measurement or protection. There is high impedance inserted between the earth and the neutral point. There is no switching on occurrence of the first insulation fault. It is therefore important to carry out permanent insulation monitoring, show the first insulation fault and locate and clear the first insulation fault.

Pros and cons: The advantage of using this one is that it provides services by tripping only when the second fault occurs which is subject to the capacity of the network not leading to a high earth fault current which would be dangerous for people when the first fault occurs. It has its demerits. There is the risk of high internal over-voltages. Insulation monitoring is also compulsory as well as the presence of maintenance personnel who will be monitoring and locating the first fault during use.

It is also known as direct earthing. It has a connection between the earth and the neutral point. Upon first insulation fault occurrence compulsory switching must be done. It is significantly different from the above mentioned unearthed neutral.

Pros and cons: This system reduces risk of over-voltage occurring and also authorizes the use of equipment with a normal phase to earth insulating level. On the other hand, there is mandatory tripping upon occurrence of the first fault. The touch voltages developed are very high and this poses a high risk for the personnel while the fault lasts. Differential protection devices must be used so that the clearance time of the fault is as short as possible.

This system requires a resistor to be inserted between the neutral point and the earth. It is also known as limiting resistance earthing. Their operating technique is quite straightforward. Switching must be done upon the occurrence of the first fault.

“SOLID” was the word Ken used to describe himself.  He is a man of character who always finishes what he starts and keeps his word.  A true humanitarian and dedicated businessman, Lebersfeld accepts this award with humble gratitude.

He continues to work six days a week, providing a “solid” foundation for his employees, as well as his younger siblings and cousins who work at Capitol Lighting.  They know–if there is a problem, whether personal or business–Ken would be there wholeheartedly and in full force.  He does nothing half-way.  And, perhaps that is why he is at the helm and has become the strong-hold of a family lighting business that has strived to be the best for over 90 years.

Today, many property owners opt for home automation systems. This is the “Internet of Things” and the manner in which various appliances, devices, and installations in your home are networked together; it provides you efficient control over various aspects of your home.

In terms of simple appliance control and lighting, this concept has been around for decades. It’s only in the recent years that there has been a sea change in this technology and you can now opt for systems that allow you complete control of your home from any remote location. Using home automation, you are able to control how a particular device will react, and why and when it should react.

Once the system has been installed, you only need to set the schedule. The rest of it is all automated and will be based on your personal preferences. This is why home automation can alert you about the events that you may want to immediately be aware of, such as unexpected access to your home, water leaks etc. All you have to do is grab your Android device or iPhone or any other remote control and alter the settings in your home. If this isn’t convenience, what is?

Let’s take a closer look at what the benefits of home automation systems are:

You are able to automate and control almost every single appliance and device in your home, regardless of where you are. You don’t really have to worry about getting up from your comfortable couch to dim the lights, draw the curtains or adjust the temperature of the room you are in, or in any other room of your house. You would be able to adjust the temperature in all the rooms in your house, just with the touch of a button on your phone.

Your CCTV cameras can be connected to the automation systems and in case there is any trespasser on your property, you would be immediately alerted to it. Your water sensors could be connected as well and you would immediately know if there was a leak, even if you aren’t at home; this gives you the chance to react and safeguard your home very effectively.

Home automation can help you switch on and off lights and sprinklers etc. when you want to, even when you aren’t actually at home. You can also switch on the air conditioning or water heater a few minutes before you are slated to reach home, and that helps save energy too as you wouldn’t have to keep the hot water system running all day. This kind of functionality helps you save on your utility bills.

When you have a home automation system installed on your property, you know you are using the latest technology. While the working of these systems is quite complex, the systems themselves are very user-friendly and this makes for a fun experience. You will find yourself impressing your guests with the various features of the system and enjoy using the automated systems.

Prefabs provide on-site, off-site and other hidden advantages. For instance, faster installation at the job site reduces the project duration. Prefabs have the potential of cutting the installation time by almost a half. In addition, the project will require fewer workers in the field resulting in a big reduction in labor costs and improved profitability.

There’s also a significant savings on labor, which can be very expensive and in short supply. The prefabrication process is considered more of a manufacturing function so the contractor is able to achieve success with fewer workers. The workshop can make use of semi-skilled workers and apprentices, unlike a construction site where an electrician is required to perform the installation.

Fewer materials and less activity at a job site mean that the project is completed faster with a reduced opportunity for accidents and delays. In addition, by delivering all the individual components to the workshop for assembly, the level of material handling is narrowed. This equates to an easy-to-manage supply chain. Fewer materials reduce clutter, waste disposal, and the need for extra storage space.

The workshop provides the best environment for producing the assembly fast without the interruptions that might be found at a construction job site. Further, the production of prefabs is not affected as much by delays from other trades, bad weather, and other construction project hold-ups.

Electricians spend less time working at dangerous heights and precarious positions, hence reducing safety risks. Prefabs allow contractors to reduce the need for as many licensed electricians on the job site. This can result in greater productivity and profitability.

Increased competition and high labor costs have caused declining profits for many electrical contractors. However, with the use of prefabs, profitability can be improved by reducing the labor and time spent at the construction site. Additionally, fabricating electrical assemblies in a workshop makes it easier to stay on budget and hit your project timelines.
