Trinity Energy Systems [P] Ltd manufactures Electrical Power Meter with Multiparameter Monitoring. Trinity Energy Systems [P] Ltd is ISO 9001:2000 certified that offers electronic power and energy meters and power factor controllers. The Electrical Power Meter with Multiparameter Monitoring under the model name Empower is designed for use in three phase three/four wire electrical systems. It measures the phase voltages, currents, PF, Hz, system KVA, system KW, system KVAr, Active Energy [Kwh] and Apparent Energy [KVAh]. The various parameters measured are displayed on a 4 digit x 3 Row Red 7 segment LED matrix for easy visibility and readability. The CT ratio [primary] can be programmed at site using the front membrane key. 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 1.0 for all parameters including Kwh.
