How Do Uninterruptible Power Supplies Work?

Even with perfect preparation and the highest quality office fit out cabling, you cannot prevent power outages. These may come from issues in the grid or fuses and switches being tripped in the building’s power supply. If the power is interrupted for any of these reasons, it could cause severe damage to sensitive equipment like computers, industrial control systems, and servers. Uninterruptible power supplies are the best way to ensure constant and stable power gets to these pieces of equipment.

Power issues in office fit out cabling are not always just outages. Most office equipment expects the Australian standard of 230 volts at 50 Hertz for power. If the voltage drops below this (called a sag or brownout) or raises above (called a surge) there may be damage to sensitive equipment. There are also frequency changes which can cause issues. Uninterruptible power supplies aim to supplement or replace the mains power in these cases to keep equipment online.

There are a few different types of uninterruptible power supplies, depending on the sensitivity of the equipment and protection needs:

  • Standby systems – are only activated when an issue is detected, replacing the mains power with battery power. The DC power from the battery must be inverted to AC before being fed to the machines. Standby systems are the most basic and are used in entry-level and consumer equipment.
  • Line-interactive uninterruptible power supplies – a built-in transformer supplements slight fluctuations and engages the battery when power is lost. This is used for mid-range network equipment and office data systems.
  • Double conversion – power is passed through the battery at all times by being converted to DC then back to AC. This has zero switch-over time and gives the best protection for high-end server, data, and telecommunications equipment.

Data Cabling Sydney – Different Cable Standards

Network connections make many business’ IT solutions possible, with any wired access to the internet or internal servers requiring data cables. Data cabling Sydney follows a range of standards for speed, distance and interference reduction, these are laid out by national and international bodies. For the speed and capacity required by many businesses, Wi-Fi connections simply aren’t sufficient. To mitigate this, wired network cabling solutions are needed. In general, the cables used for internet connection and data cabling Sydney are known as Ethernet cables. These come in a range of categories.

  • Cat5e – and advancement of the previous cat5 cables, these are the earlier standard still recognized today. They have completely replaced cat5 and are the most commonly used in data cabling Sydney at the moment. They support speeds of up to 1Gbps.
  • Cat6 – a major improvement on its predecessor, these cables can be shielded to prevent interference and can support maximum speeds of 10Gbps for 50 metres, or the 1Gbps of the previous standard for 100 metres.
  • Cat6a – a revised version of the previous standard which allows longer transmission at its highest speeds and implements much better shielding and crosstalk elimination.
  • Cat7 – a very new standard where each fibre is individually shielded to ensure maximum integrity of data. These can only transmit at shorter distances but can do so at up to 10Gbps.

Commercial Office Fit Out – 2 Essential Elements

Office electrical and data systems are often very large systems. The plethora of varying connections tends to make them confusing for many business owners. There are a few essential elements to any commercial office fit out which will keep your business running smoothly and safely. GM Cabling who provides network cabling Sydney can supply and install many of these systems for your business.

Network Cabling

Most commercial office fit out systems must be wired together to function correctly, this includes internet, phone, and server connections. Network cabling Sydney suppliers such as GM Cable can install and connect such systems to keep offices running smoothly and efficiently. Network cables come in many versions for different tasks; the main ones are Cat5e, Cat6, Cat6a, and Cat7. Higher numbers indicate newer versions that have larger bandwidths and better transmission speeds. Cat6a is capable of transmitting larger distances up to 100m with no loss, which may be very desirable in network cabling Sydney. Cat7 is a very new standard offering much higher speeds but at considerably shorter distances.

Uninterruptable Power Supplies (UPS)

These systems are staples of many commercial office fit out as they are great for offices with important computer systems or servers which must remain online at all times. They are placed between the mains power and the computer/server. In the event of power interruptions, they keep the machine powered until a secondary power source can be started or the machine is shut down safely. This is great for protecting important files and devices in your office network.

Structured network cabling solutions in the home

Why network cabling?

Network cabling solutions in the home is required mainly because of two reasons – speed and reliability on network. Network cabling is one of the fastest using cable networking than Wi-Fi connection and is not affected by the wall, distance, interference from other sources, or competing Wi-Fi networks.  It’s much faster and much more reliable. The motive is to have network port usage. It is also important to note that network cabling is also reliable for file sharing. Network cabling in Sydney distributes all sorts of services around the home including phone, TV, HDMI, Poe and probably it includes other stuff in the future.

According to NSW network cabling rules in Sydney, it’s mandatory to have your home cable fixing to be done by registered professional network cable installer, because it involves underfloor, in-wall or in-roof cabling by registered cable solutions.

The structured cable network types

If you decide to install network cabling in your home you will be asked whether you want so-called category-5, category-6, or category-6a cable. These are standard government rules for any physical construction of the cable and how fast it will carry the data around the home. There is one more network cabling solution referred to an Ethernet overpower or EoP, which used an adapter to convert voltage from the main wiring into a network of sorts.

It’s also important to note that network cabling is a generic means of distributing all sorts of services around the home including phone, TV, HDMI, PoE (Power over Ethernet), and probably others in the future. GM Cabling Solutions is a registered network cabling installer in Sydney, which fulfil all your needs as per standards.

How to wire an electrical Distribution Board?

Distribution Board is an electricity supply system or a common inclusion that distributes the electrical power feed into subcircuits. There are different distributor boards:

A main electrical distribution board (MEDB)

Sub electrical distribution board (SEDB)

A final electrical distribution board (FEDB)

The Phase and Neutral supply lines are fed to the Distribution board through the service drop running from the utility pole. It is then connected to the energy meter through a fuse.

In the second phase, the neutral line from the energy meter is directly connected to the main isolator. The isolator is used to open and close the lines manually, which is the main switch of the electrical system for network cabling solutions.

Once the isolator is connected to the residential current board, then the residential current board device used to protect from current leakage from the circuit.

For electrical distribution board, wiring below accessories is required, like fuses, isolators, circuit breakers, single-pole MCB, miniature circuit breaker, and circuit breaker.

Guide to installing commercial electrical distribution boards

The whole set up process of electrical distribution boards has been changed in the past few years. There are more secure protected ways of panels we can use.

Electrical Distribution Boards installation Process need a selection of proper equipment along with the manufacturer’s instructions. Designers and installers must select a wiring system that avoids damage to the sheath and insulation of cable during installation, use, and maintenance. Where cable enters a distribution board from trunking, the cables must be protected from any sharp edges in order to comply with board setups.  There are proper diagrams that need to be followed while designing the electrical board circuit.

Skills and Instructed Person Requirements for Electrical Distribution Boards

Where there are large fault currents required, you should also consider the type of person who will operate the devices, manage the faults in distribution boards. Though manufacturers are responsible for ensuring the capacity of the equipment between the incoming and outgoing current terminals for the electrical distribution board, which includes busbars and connections as well as incoming and outgoing devices.

NSW standards rules for installing Electrical Distribution Boards

To ensure that the electrical installation of a customer can be connected to the distribution system, the electricity distributor can describe the requirements of the connection to its system and compatible requirements of the electrical installation process. Certain rules for installation process –

  1. By providing consistent requirements from electricity distributors.
  2. Specifying electrical installation requirements as approved by the department.
  3. Complete information should be provided by electricity Supply Company, metering providers, etc.

What does electrical distribution board works?

An electrical distribution board is a panel-based board that controls the electric power feed and equally distribute in circuits. Often, there are also local regulations as to how these boards are configured by professionals who do electrical works on a regular basis that delivers quality and suitable flow of electricity in a circuit.

The electrical Distribution board at home is different from comparing one in commercial places like restaurants, shops, etc. All internal and external lighting systems shall be designed to enhance safe movement, personal safety, and security for any electrical distribution board designing. The distribution board shall be tested before use, the construction arrangements should be proper. A most important point to remark for all electrical distribution boards is that they are made with large enough space( cater) for main incoming and outgoing cables and the positioning of transformers, terminal blocks, and contractors so that cable to these items can be done in a proper manner and it works appropriately incomplete circuit of current flow.

The above description is inapplicable for both wall-mounted or underground electrical cable solutions. All light and power circuits are to be loaded to less than 75% of their rated capacity. Visit our website on GM Cable and get your electrical distribution board done.
