5077 Images

  • A high accuracy AC and DC power calibrator suitable for calibrating single-phase watt-meters, power meters, and kW-Hr meters. The 5077 is a practical solution to precision power simulation, providing a simultaneous supply of voltage and current with phase control. The unit is operated via a virtual control software application allowing the user full control via laptop or PC.

    The 5077 voltage range is 20 mV to 1050 V, with current from 20 mA to 22 A. Frequency can be set in 0.01 Hz steps from 40 to 400 Hz, and phase in 0.1° steps. Alternatively power factor (PF) can be set in steps of 0.01. The output can be displayed as VA or Watts. The wide current and voltage ranges enable verification of power meters on either the primary side of the of the CT / VT or directly connected to the meter (secondary side).

    The standard maximum AC current output (22 A) can be extended to 100 A by using an optional 100 A current transformer. This extends the maximum power to 0.1 MW/MVA. A single and 50-turn current clamp adaptor is available for clamp sensor and meter calibration up to 1100 A.

    PC/Laptop Virtual Control Panel
    A simple user interface application that enables the operator to control the 5077. Select functions, set and output values as required.

    EasyCal Calibration Software
    The 5077 can be controlled via Time Electronics EasyCal software to automate the calibration process. This provides increased speed of calibration and consistency of results. Produce traceable calibration certificates and test reports for quality standards with additional uncertainty information for ISO 17025 conformance.
     

  • Technical Specifications

    Specifications apply to 5077 models that feature both low and high current terminals (year 2020 onwards).
    Accuracy specifications are shown as ±(% of output + floor). Specifications apply at 23 °C ± 5 °C. All values are relative to calibration standards.

    The accuracy of the power is complex and is determined by using a formula, which combines the errors due to Voltage, Current, and Phase.
    Power Accuracy (%) = SqrRt (Voltage accuracy² + Current accuracy² + Phase Correction²).
    Where Phase Correction (%) = 100x(1-Cos(Phase+PhaseAcc)/Cos Phase).
