Digital Voltage Indicators – DVI-500 Series
The DVI-500?Series Digital Voltage Indicators are?single point instruments designed to read the voltage on a conductor up to 500kV line-to-ground. The large LED readout is easy to read on the end of a long hotstick and can be used on overhead lines or in underground applications with an underground bushing probe.
There are two DVI-500?models. The DVI-500 indicates voltage from 0.1kV – 500kV on overhead and underground systems – displaying the voltage on a large 3-digit LED display.?The DVI-500T with Test Point Mode?has the added feature of?indicating voltage on elbow test points.
The DVI displays the voltage and emits an audible alarm when voltage above 100VAC is detected with no range selector switches or settings to be made – just contact the conductor and read the display. This allows the user to determine if the voltage being read is nominal or a lower induced voltage.
The DVI-100 Series Digital Voltage Indicators indicate voltage up to 99kV on a two-digit display.
Digital Voltage Indicator Features
- For use on system voltages up to 800kV
- Large LED display indicates the line-to-ground voltage level
- Display is easy to read in bright or dark conditions
- Voltage readout allows user to distinguish between nominal and induced voltage levels
- Audible indication of voltage detected
- Built-in universal spline for standard hotstick attachment
- Auto shut-off with low battery function
- DVI Voltage Detector?Tester (PT-DVI, optional) available as a power source to test the DVI before and after use

数字电压指示器 – DVI-500系列
DVI-500系列数字电压指示器是单点仪器,用于读取导线电压高达500kV的线对地电压。大型LED读数器在长热棒的末端易于读取,可用于架空线路或地下应用中的地下衬套探头。
有两种DVI-500型号。DVI-500表示架空和地下系统的电压为0.1kV – 500kV – 显示大型3位LED显示屏上的电压。具有测试点模式的DVI-500T具有在肘部测试点上指示电压的附加功能。
当检测到高于100VAC的电压且没有范围选择开关或设置时,DVI显示电压并发出声音警报 – 只需接触导体并读取显示屏。这允许用户确定所读取的电压是标称电压还是较低的感应电压。
DVI-100系列数字电压指示器在两位数显示屏上显示高达99kV的电压。
数字电压指示器功能
- 适用于高达800kV的系统电压
- 大型LED显示屏指示线对地电压水平
- 在明亮或黑暗条件下,显示屏易于阅读
- 电压读数允许用户区分标称和感应电压电平
- 检测到电压的声音指示
- 内置通用花键,用于标准的热棒附件
- 自动关闭,电池电量低
- DVI电压检测测试仪(PT-DVI,可选)可用作在使用前后测试DVI的电源
