The 2020–21 Singapore circuit breaker measures were a stay-at-home order and cordon sanitaire implemented as a preventive measure by the Government of Singapore in response to the COVID-19 pandemic in the country on 7 April 2020. The measures were brought into legal effect by the Minister for Health with the COVID-19 (Temporary Measures ...
The COVID-19 pandemic in Singapore was a part of the worldwide pandemic of coronavirus disease 2019 caused by severe acute respiratory syndrome coronavirus 2 . The first case in Singapore was confirmed on 23 January 2020. Early cases were primarily imported until local transmission began to develop in February and March.
It was estimated by the economist Chua Hak Bin, the Singapore circuit breaker measures in response to the pandemic, beginning on 7 April could impact the economy to the tune of S$10 billion. [80] With the lockdown imposed on construction workers, there were concerns that there could be delays in construction projects of up to six months. [81]
A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by current in excess of that which the equipment can safely carry ( overcurrent ). Its basic function is to interrupt current flow to protect equipment and to prevent fire. Unlike a fuse, which operates once and then must be replaced, a ...

A transient recovery voltage ( TRV) for high-voltage circuit breakers is the voltage that appears across the terminals after current interruption. It is a critical parameter for fault interruption by a high-voltage circuit breaker, its characteristics (amplitude, rate of rise) can lead either to a successful current interruption or to a failure ...
On 3 April 2020, a stringent set of preventive measures collectively called the "circuit breaker lockdown" was announced. [173] Stay-at-home order and cordon sanitaire were implemented as a preventive measure by the Government of Singapore in response on 7 April 2020. The measures were brought into legal effect by the Minister for Health with ...
Circuit breakers are essential elements of high-voltage power systems because they are the only means to safely interrupt a short circuit current. The international standard IEC 62271-100 defines the demands linked to the characteristics of a high voltage circuit breaker. [7] The circuit breaker can be equipped with electronic devices to know ...
