Three Phase Digital Ammeter
Indotech Three Phase Digital Ammeter – Digital 3 Phase Ammeter is used in an inductive circuit to measure the value of the power factor. The three ammeter is also used in an inductive circuit to measure the value of the power factor, independent of source frequency and waveform.
Our three phase digital ammeters 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 Ammeters require to be used for three phase system.
TYPE OF METERS : THREE PHASE DIGITAL AMMETER
1. THREE PHASE SELECTOR SWITCH TYPE AMMETERS :
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 THREE DISPLAY AMMETERS :
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.
