The first thing you should do is turn off all power to the affected area immediately Then, call a professional electrician to come out and assess the situation They’ll be able to determine whether the problem can be fixed or if you need to replace the entire distribution board completely In either case, they’ll be able to get your power back up and running quickly so that you can get back to normal operations as soon as possible


Commercial Electrical Projects Require a High Level of Expertise

Electrical distribution board failures can occur for a variety of reasons, from poor installation and maintenance to extreme weather conditions The most common cause of electrical distribution board failure is inadequate maintenance Regular cleaning and inspection of the board and its components can help prevent problems Extreme weather conditions can also cause electrical distribution board failures High winds, heavy rain, and lightning can damage the board or its components If an electrical distribution board fails, it can cause a power outage or other serious problems It is important to have a plan in place for dealing with such failures In conclusion, proper installation and regular maintenance are the best ways to prevent electrical distribution board failures However, if a failure does occur, it is important to be prepared and know how to deal with it promptly and safely

Electrical distribution board failure can have many causes, but there are some common preventative measures that can be taken to help avoid these failures Some of the main causes of electrical distribution board failures include overloaded circuits, loose connections, and poor maintenance To help prevent these failures, make sure to keep your circuits well-organized and updated, check all connections regularly, and always follow good maintenance practices


Electrical distribution boards are one of the most important parts of a machine. They are used in every machine to send electricity to all parts of the machine. If they stop working, machines can stop working. This is why you have to know how to address and fix any electrical distribution board failure.

An electrical distribution board needs a voltage, and it works best at a certain temperature range. Failure might happen when voltage is too low or too high, or when there’s no power coming through at all due to a broken wire or loose connection on the electrical distribution board.

There are various ways that you can address an electrical distribution board failure – rotating an electrical plug, replacing the electrical cord, tightening screws, replacing an electrical cord connector, disconnecting and reconnecting an electronic device on an electric outlet with no additional cost

I'm really glad to have found Electrogem. Garth and Devin were professional, good-humoured, and worked neatly and hard - not even breaking for lunch. I really appreciated the jargon-free explanations of what was needed, and the great suggestions that I wouldn't have thought of (like replacing the old fluorescents in our stair lights with LEDs). They covered a large amount of work in a few hours and I found their pricing reasonable for the value.

Great friendly professional service. Layne and Garth didn't think twice about going the extra mile and making sure my problems were attended to.
I recently needed an Electrical Compliance Certificate for my property. A "highly recommended" company did an inspection and politely presented me with a "highly inflated" quote for remediation work. I was then referred to Electrogem. Layne Manly from Electrogem responded to my plea for help. Within a few days; Layne and his crew undertook a new inspection, completed the necessary remediation work and issued the necessary compliance certificate. The bill (including the new inspection fee) from Electrogem was substantially lower than the original quote. They are extremely professional, highly responsive and incredibly reliable. You will never go wrong by calling on Electrogem.

Electrogem have just installed a full solar PV system (panels, inverter, batteries) at my home. I found them to be very professional and the workmanship to be of the highest standard. Layne Manley is knowledgeable and approachable, and his staff (Garth and Michael) were meticulous in performing the installation. I can unreservedly recommend Electrogem .

Equipment failures: Causes

Every piece of electrical equipment in a distribution system is susceptible to failure. A piece of equipment that is not properly installed can be damaged during shipping or poor manufacturing. Equipment can sometimes fail without warning due to a variety of reasons, including thermal age, chronological age, chemical decomposition, and others.

Distribution Transformers
  • Two ways that transformers can impact reliability of distribution systems are overloads and failures

  • In the event of a catastrophic transformer failure, thousands of customers could be affected.

  • If there isn’t enough spare capacity for transformers, it must be decided whether to overload them and accept the loss of life.

  • Accepting the loss of life will increase reliability, but it will also increase the likelihood that overloaded transformers will fail in the future.

  • Transformer ratings are determined based upon the expected life span of winding insulation at a specific temperature

  • Ratings assume an ambient temperature between 30 and 65 degrees Celsius, an average winding temperature increase of 55 to 65 degrees Celsius, and an additional hot spot temperature rise of 10degC/15degC.

  • A transformer’s life expectancy is defined as the time it takes for the insulation material to lose half of its mechanical strength.

Underground Cable
  • Treeing

  • Extruded dielectrics, such as cross-linked plasticethylene (XLPE), or ethylene-proplene rubber (EPR), can be harmed by moisture. This causes the cable’s voltage withstand ability to drop.

  • Cable manufacturers created jacketed and tree retardant cables (TR-XLPE) to address utility concerns.

  • Insulation voids and insulation impurities accelerate moisture absorption, which can significantly reduce the cable’s life expectancy.

Overhead Lines
  • High exposure results in most overhead line damage being caused by external factors like animals, vegetation, and severe weather.

  • High currents can cause lines to sag which reduces ground clearance and increases the likelihood of phase conductors coming into contact.

  • If not cleared quickly, fault currents can cause conductors fuses and to burn down.

Circuit Breakers
  • The most common causes of failure are circuit breakers that open incorrectly (false trip) and those that fail in service (not opening/closing).

  • The next most frequent failures are caused by internal faults.

  • Circuit breakers may also have internal faults that prevent them from opening or closing.

  • Continuous monitoring can be used for estimating circuit breaker condition, including cumulative loss of contact materials.

Surge Arresters
  • Two basic types of surge arresters are silicon carbide (MOVs) and metal oxide varistors.

  • To avoid excessive currents in normal operation, silicon carbide arresters need an air gap

  • MOVs exhibit a nonlinear resistance. The MOV’s resistance drops sharply when the voltage is higher than a threshold. This is similar to a Zener diode.

Insulators and bushings
  • They are made of three main materials: polymeric, porcelain, and glass.

  • Although contaminated conductors perform well, dielectric strength decreases as the contamination progresses.
