For example, in North America, a unique split-phase system is used to supply to most premises that works by center tapping a 240 volt transformer. This system is able to concurrently provide 240 volts and 120 volts. Consequently, this allows homeowners to wire up both 240 V and 120 V circuits as they wish (as regulated by local building codes).
As in the UK, 240 V is within the allowable limits and "240 volt" is a synonym for mains in Australian and British English. In the United States [ 12 ] [ 13 ] and Canada, [ 14 ] national standards specify that the nominal voltage at the source should be 120 V and allow a range of 114 V to 126 V ( RMS ) (−5% to +5%).
The general public may consider household mains circuits (100 to 250 VAC), which carry the highest voltages they normally encounter, to be high voltage. Voltages over approximately 50 volts can usually cause dangerous amounts of current to flow through a human being who touches two points of a circuit, so safety standards are more restrictive ...
Portable transformers that transform single-phase 240 V to this 110 V split-phase system are a common piece of construction equipment. Generator sets used for construction sites are equipped to supply it directly. However, a large farm may be given a 230–0–230 (nominal) supply.
The National Transmission Corporation (Filipino: Pambansang Korporasyon sa Transmisyon, also known as TransCo) is a Philippine government-owned and controlled corporation established in June 26, 2001 by the Electric Power Industry Reform Act (Republic Act 9136) and a corporate entity wholly owned by the Power Sector Assets and Liabilities Management (PSALM).
The Philippines is firmly committed to negotiations for a code of conduct between China and Southeast Asian countries to avert confrontations in the South China Sea, its foreign minister said on ...
A linear circuit must be designed for a specific, narrow range of input voltages (e.g., 220–240 VAC) and must use a transformer appropriate for the frequency (usually 50 or 60 Hz), but a switched-mode supply can work efficiently over a very wide range of voltages and frequencies; a single 100–240 VAC unit will handle almost any mains supply ...
MANILA (Reuters) -The Philippines has approached neighbours such as Malaysia and Vietnam to discuss a separate code of conduct regarding the South China Sea, its president said on Monday, citing ...
