    • A device for interrupting a flow of electrical power in an electrical distribution system is provided. The electrical distribution network includes a circuit interrupting device, the circuit interrupting device having a reclose time. The device includes a sensor configured to generate a signal in the event of loss of system power. A switch is coupled to the electrical distribution system and is movable between an open and closed position. A controller is operably coupled to the sensor and the switch, the controller having a processor that initiates a timer in response to the signal and determines a measured reclose time with the timer. The processor is further responsive to actuate the switch in response to the measured reclose time is substantially equal to the reclose time of the at least one circuit interrupting device.
    • 提供一种用于中断配电系统中的电力流动的装置。 配电网络包括电路中断装置,电路中断装置具有重合闸时间。 该设备包括被配置为在系统功率损失的情况下产生信号的传感器。 开关联接到配电系统并且可在打开和关闭位置之间移动。 控制器可操作地耦合到传感器和开关,控制器具有响应于该信号启动定时器的处理器,并且与定时器确定测量的重新关闭时间。 响应于测量的重合时间,处理器进一步响应于致动开关,其基本上等于至少一个电路中断装置的重新闭合时间。

    • Systems and methods for making and using manhole safety gratings are described. Each safety grating includes a plate that has a first surface, a second surface, and a perimeter edge that extends between the two surfaces. The plate also defines a plurality of vents that extend between the first surface and the second surface. The plate can have any suitable shape or size that fits within the desired manhole. The plate can comprise any suitable material and be any suitable weight that provides the desired protection to the manhole. The safety gratings can therefore provide temporary safety for the manhole when they are used in place of permanent safety gratings. Other embodiments are described.
    • 描述了制造和使用人孔安全光栅的系统和方法。 每个安全光栅包括具有第一表面,第二表面和在两个表面之间延伸的周边边缘的板。 板还限定了在第一表面和第二表面之间延伸的多个通风孔。 该板可以具有适合于所需人孔内的任何合适的形状或尺寸。 板可以包括任何合适的材料,并且是向井眼提供期望的保护的任何合适的重量。 因此,当安全栅被用于代替永久安全光栅时,安全栅可以为人孔提供临时安全。 描述其他实施例。
