What is Body Protection in a Medical or Dental Environment?

COMMERCIAL NEWS RESOURCES

One question we are commonly asked when quoting for medical and dental fit outs is ‘what is Body Protection?’

Basically, Body Protection means that every power point in every medical or dental treatment room is protected by a special safety switch.

These particular safety switches are a lot more sensitive to earth leakage currents than those on a residential or office power point thus protecting you, your staff and patients from any chance of an electrical shock while treatment is taking place.

Body Protection is a requirement of the Standard AS/NZS 3003.2011 and therefore compulsory for any new medical or dental fit-out.

What is Power Factor Correction?

When you pay for a latte, the last thing you want is more froth than coffee. The same thing can be said about power. Froth on a latte is like wasted energy.

As well as the power that is used in equipment (heating, lighting, driving motors), known as real power, a site may also draw power which is not directly used, known as reactive power.

The combination of two is known as apparent power. Power Factor is the relationship between real and apparent power (kVA). If your site has a poor power factor, you could be paying for energy that cannot be used.

Power Factor Correction Equipment: FAQ

COMMERCIAL INDUSTRIAL NEWS RESOURCES

What is Power Factor and how does PFC Equipment work?

The Power Factor of an electrical installation is the ratio between the power that is actually used (kW) and the power that is supplied (KVA). It is a measure of how efficiently an installation uses Electrical Energy.

Power factor equipment supplies the reactive current (eg. magnetising current required by electric motors to turn but does no real work) required by an installation that is normally supplied from the supply transformer and therefore passes through the electricity meters.

Reducing this magnetising current through the electricity meters and the switchboard will reduce the cost if the tariff is based on KVA Demand (or apparent power). The power actually used is the “real” Power (in watts). The power supplied is the “apparent” power (in Volt-Amps).

Power Factor = Real Power (kW)/Apparent Power(KVA)

What is an incandescent light bulb?

The incandescent light bulb or lamp is a source of electric light that works by incandescence, which is the emission of light caused by heating the filament. In a normal incandescent lamp, the filament is made of tungsten metal and surrounded by a nonreactive (inert) gas such as argon. They are made in an extremely wide range of sizes, wattages, and voltages.

Why are incandescent light bulbs not energy efficient?

The problem with incandescent light bulbs is that the heat wastes a lot of electricity. Heat is not light, and the purpose of the light bulb is light, so all of the energy spent creating heat is a waste. Incandescent bulbs are therefore very inefficient. They produce perhaps 15 lumens per watt of input power.
