电能质量

Indications of a power quality problem could be as subtle as lights dimming or momentary power outages.

Quality issues can arise from many events such as lightning strikes, the starting and stopping of heavy equipment, 电路过载, 或接线不当. Whatever the case may be, power quality problems can be disruptive to our daily activities.

To report an issue stemming from power quality to your home or business, please contact 真人百家家乐APP下载’s 客户服务.

电能质量很重要

We understand that having access to a safe and reliable supply of power is important to our customers. That’s why we endeavor to maintain a distribution grid that delivers electricity at the customer’s service entrance with consistent quality and reliability.

In cases where customers require higher reliability or security of electricity supply, other than the standard provided by 真人百家家乐APP下载, they are responsible for their own back-up, 备用设备, or special protective equipment for their electrical devices to minimize the effects of momentary power outages, a相损耗, 电路过载, power surges and other disturbances.

电能质量——它是什么?

真人百家家乐APP下载 has defined the scope of power quality to include voltage limits, 电压畸变, and current distortion as measured at the customer’s service entrance.

Power quality investigations

真人百家家乐APP下载 will respond to all power quality concerns and verify the power supply at the customer’s service entrance.

We will use appropriate industry standards as per our 电能质量 Guideline (ECG0008) while maintaining power quality on the distribution system. If the source of the power quality problem is from our electricity supply, and where industry standards are not met, 我们会纠正这个问题.

If the power quality problem lies on the customer side, the customer will be responsible for rectifying the problem.

场杂散电压

Customers who suspect high levels of stray voltage, also known as “tingle voltage” on farms, can request an investigation. Further details are available at cn-wanshun.com/farms.

预防问题

With proper wiring and grounding, most power quality problems can be eliminated.

The customers must ensure that their electricity usage or distributed energy resource facility does not adversely affect the distribution system. Customers with large non-consistent loads or a distributed energy resource facility must maintain acceptable power quality by implementing proper corrective measures, such as installing proper filtering and/or grounding or protection.

也, the customer is to ensure that the starting current of any motor does not exceed their associated distribution supply circuit limitations. The customer can also experience voltage flicker on their secondary system if the motor(s) are supplied from a transformer bank which also supplies lighting or other sensitive equipment.
