| (1)带电对高压计量箱查看或在二次回路上进行丈量时，应由两人进行，并注意人体与带电设备的安全间隔。 (1) when checking the high-voltage measuring box with electricity or measuring on the secondary circuit, two people shall be responsible for it, and pay attention to the safety interval between the human body and the charged equipment. (2)带电丈量与作业时(在二次回路)应戴绝缘手套，运用绝缘工具。 (2) wear insulating gloves and use insulating tools during live measurement and operation (in the secondary circuit). (3)制止在运转中的电流互感器二次回路上开路作业。 (3) prevent the open circuit operation on the secondary circuit of the current transformer in operation. (4)一般高压计量箱未装失压记录仪，当电能表失压时无法确定时间，对追补电量时带来一些困难。因而，每隔1～2月要对高压计量箱的电压互感器的熔断器进行一次查看、丈量，雷雨时节应增加查看丈量次数，以便及早发现与解决。 (4) in general, the high-voltage measuring box is not equipped with a loss of voltage recorder. When the power meter loses its voltage, the time cannot be determined, which brings some difficulties to the power recovery. Therefore, it is necessary to check and measure the fuse of the voltage transformer of the high-voltage metering box every 1-2 months. In thunderstorm season, it is necessary to increase the times of checking and measuring so as to find and solve the problem as soon as possible. (5)当发现高压计量箱故障异常时(包含二次回路失压、失流、电能表毛病等)，应告诉用户参与核实，以防止追补电量时带来的纠纷。 (5) in case of any abnormal fault of high-voltage metering box (including secondary circuit loss of voltage, loss of current, electric energy meter fault, etc.), the user shall be informed to participate in the verification, so as to prevent the dispute caused by power recovery. (6)每次查看与丈量和试验时，都要有记录，以便与运转历史记录正常数值进行比较。 (6) each time when checking, measuring and testing, there shall be records to compare with the normal value of operation history record. |
