1. INTRODUCTION
1.1 Electricity Distribution Networks
The electricity distribution industry is one of the largest in the UK, serving nearly 27 million customers. In England and Wales, there are 12 regional electricity companies responsible for distributing and supplying electricity to customers. Electricity i s received from
the transmission network at 132 kV and is transformed down to lower voltages, i.e. 33kV, 1 IkV and 240V, as it is distributed across a region. 132kV and 33kV are referred to as High Voltage (HV) and 11 kV and below
as Low Voltage (LV). Domestic customers receive their supply at 240V and some large industrial customers can take their supply at either 11 kV or 33kV.
On the high voltage networks (132kV, 33kV), the circuits are usually equipped with automatic circuit breakers that report their operation to the control centre via the Supervisory Control and Data Acquisition (SCADA) system. These circuit breakers are fitted with an auto-reclosure

1.1配电网络
配电业是其中一个最大的在英国，服务的近2700万的顾客。在英格兰和威尔士，有12个区域电力公司的负责分发和供应电力给客户。电力i s收到
输电网络，在132千伏和转化下降到较低的电压，即33kv ， 1 ikv和240 V的，因为它是分布在整个地区。 132千伏电力和33kv被称为高电压（高压）和11千伏及以下
作为低电压（ LV ）号。国内客户接受他们的供应在240 V的和一些大型工业客户可以采取他们的供应无论是11千伏特或33kv 。
对高压网络（ 132千伏电力， 33kv ） ，电路通常配备自动断路器，该报告他们的行动控制中心，通过监控与数据采集（ SCADA系统）系统。这些断路器装有自动重合闸，这意味着他们自动打开，由于发生故障，在短暂的延迟后，他们将重合闸在试图恢复供应。如果故障是暂时性的，断路器将继续停止使用和电力将被恢复，但如果它是永久性的，然后断路器将再次重开中断供应。
与低电压网络（ 1千伏及以下） ，往往只即将离任的来源，断路器，对11千伏馈线从主要变电站，是遥测。下面来源断路器网络是径向与许多分行导致1 lkv / 415v变压器供应客户，这些分行所保护的保护装置，如保险丝，不属于遥测。
