Vam electro devices is a supplier of electronic single phase kwh meter type vam-ilre. Structural features of the electronic energy meter from vam electro devices: the electronic energy meter consists of three sections, i.E., power supply, measurement section and display section. The power supply section feeds the power to the measurement and display sections from the input voltage with a minimum possible burden. The measurement sections is connected to the basic voltage and basic current signals of the input phase with respect to the neutral in the mode of 1 phase 2 wire configuration. In this process the power factor is taken into consideration while calculating the power usage. Thus output pulse rate follows the instantaneous power measured and the same is utilised to drive an electromagnetic impulse counter or stepper motor driven counter in the display section. The display section consists of an electromagnetic impulse counter which registers 6 digits [five full digit and one decimal digit]. That implies that the digital display of the electronic energy meter from vam electro devices is capable of reading 99999.9 [almost one hundred mega watthour with a resolution of one tenth of a kilowatthour].Technical specifications of the electronic energy meter: reference standard - is 13779; voltage - 240 v 50 hz; current: 5 40 a, 5 30 a; starting current - 0.4% lb; and power loss in voltage circuit - less than 1 w.
