True RMS Sensing. Power KW, KVAR, KVA, PF Mathematically, power factor is the ratio between kW and kVA (PF = kW / kVA). kW is the “real power†that actually does the work, kVA is the apparent power and kVAR is the PQM 3 · 3 Phase V, I, F, KVA, KW, KVAR, Energy · Programmable Relay · Low cost · RS485/MODBUS metering, 3-phase • Digital indications for: - RPM - Operating hours - Oil pressure - Coolant temperature - System DC volts - L-L volts, L-N volts, phase amps, Hz - ekW, kVA, kVAR, kW-hr The EM DataNode measures 23 parameters, including true RMS voltage and current, kW, kVA, power factor, frequency, and kVAR. Using a Signature System™ InfoNode ®, energy data from kVA = sqrt [ ( kW x kW ) + ( kVAr x kVAr ) ] Generally motors that are operated at or near full nameplate loading (e.g., a 100-Hp motor delivering 100-Hp of work) will have a V, A, kW, kVA, kVAR, PF, Hz, Total 24 Parameters • AC Current Up to 1000 A, AC Voltage Up to 600 V • Inrush (100 ms), Hold, and Peak Functions to prevent over correction Existing Existing Power Monthly Factor ExistingExistingKvar addedNewNew Peak Coincident with (Calculate) (Calculate) to kVa Power kW Monthly Peak kW kVa kVar system Features: • Large backlighting LCD displays 10 parameters simultaneously (kW, kVAR, kVA, PF plus the voltage an dcurrent of the three phases) • Clamp-on True RMS power Metering: A variety of analog and digital metering packages are available for various models for display of volts, amps, frequency, KW, KVAR, power factor, KVA, including Review of the utility company’s rate structure. Development of a graphical profile of the facilities kVA, kW and kvar. Determination of the required capacitor kvar additions for kVA = √[(kW) 2 + (kVAR) 2] The angle between the vector and the vertical axis “ A †is θ, which is the angle of deflection of the current wave form from the voltage waveform.Power Triangle Note: A right "power" triangle is often used to illustrate the relationship between kW, kvar and kVA.
