Fire that shut Heathrow was caused by a preventable technical fault known for years, report finds

London (AP) – Electrical Transformer Center Fire Heathrow AirportA report on Wednesday, the cancellation of more than 1,300 flights, was caused by a prevented technical error, which was determined almost seven years ago.

Europe’s most dense air center is closed in March about 18 hours A fire He overthrew one of the three electrical transformer centers that provided power to Heathrow. More than 270,000 passengers broke the journeys.

Anti -Terrorist Police initially directed the investigation to the fire because the authorities acted throughout Europe. Sabotage supported by Russia.

Although the authorities rapidly excluded vandalism or sabotage, the great impact of the fire was concerned about the flexibility of the Energy system of England against accidents, natural disasters or attacks.

The report made by the National Energy System Operator said that the oil samples in the transformer center in the Western London in Western London had “high moisture reading, but there was no action to replace electrical isolators known as horoscopes.

March 20, Blaze, one of the transformers, “probably” probably the moisture of the moisture that caused the short circuit causing the short circuit “causing the short circuit,” he said.

In the report, Heathrow underestimated the likelihood of losing one of the three power supplies, and consequently, “The internal electricity distribution network has not been designed or configured to benefit from having more than one supply point to achieve a quick recovery after such loss”.

Energy secretary Ed Miliband said that the findings were “deeply worried”. He said that the energy industry regulator has opened an investigation as to whether the operator of the transformer center of Ofgem has violated the license conditions of national network electricity transmission.

The National Grid said that Britain said, “It has one of the most reliable networks in the world and that such events are rare. The National Grid has a comprehensive asset inspection and maintenance program and we have taken more action since the fire.”
