THREE PHASE DIGITAL VOLTMETER
Indotech Three Phase Digital Voltmeter –3 Phase Digital Voltmeter is most suitable for measuring and monitoring three phase voltage of incoming, bus line and feeder. Digital 3 Phase Voltmeter measurement of 3 phase voltage is possible by 1 unit. 1 bar graph and 3 digital display measurements can be displayed simultaneously.
Our 3 Phase Voltmeter have been designed for monitoring the current of all the three phases. No external Voltmeter Selector Switch is required as is in the case of installation of single phase Voltmeter require to be used for three phase system.
TYPE OF METERS : 3 PHASE DIGITAL VOLTMETER
1. THREE PHASE SELECTOR SWITCH TYPE VOLTMETER:
The meter consists of single row of LED Display. The phase selection can be done with the help of “SCROLL” switch provided under the dial of the meter. A red LED lights up indicating the phase whose current is being displayed. The CT Ratio can be set with the help of “Dip Switch” provided on the back of the mete
2. THREE PHASE DIGITAL DISPLAY VOLTMETER :
The meter consists of 3 rows of LED display. Each row indicates current per phase. So the current of all the three phases is displayed simultaneously on the panel. “SELECT – CTR “ switch is provided under the dial for selecting the CT Ratio. “? A” switch is provided for the display of total current of all the three phases.
