Electrical power meter, true- RMS

Trinity Engineering is an indigenous provider of state-of-the-art equipment in power factor and power/energy management. Power Pro-XT is a true-RMS electrical power meter. This is for use in three phase four wire electrical systems. It measures the phase voltages, currents, power factors, system KVA, system KW, system KVAr and energy (kWh). The various parameters measured are sequentially displayed on a 16 x 1/16 x 4 STN LCD. The meter displays parameters in two pages with volts, amps and KWh in the first page and PFs, kVA, kW, and kVAr on the second page (in 16 x 4 model). The CT ratio (primary) can be programmed at site using the front membrane keypad. The meter uses state of the art digital signal processing (DSP) circuitry to achieve very high accuracy measurement of true RMS value of all above parameters. The meter accuracy is class 1.0s for all parameters including kWH. Processing of the parameters is done using a powerful microcontroller operating at 16 MHz. The main advantages of using the Power Pro-XT are ease of installation (only three current and three voltage inputs to be connected), economy of space and minimal wiring. Features: multi parameter monitoring; replaces eight individual meters; all parameters with accuracy class 1.0s; compact 96 x 96 DIN enclosure; micro-controller based; ideal for supervision and audit of specific loads, cost analysis and cross checking of utility billing meter; optional RS-485 port; and optional trip outputs.
