  • Page 46: Chapter 4 Applications

    Please refer to Section 4.4 for a detailed description. Since there are multiple ways to trigger the Digital Outputs on the PMC-53A-E, a prioritized scheme has been developed to avoid conflicts between different applications. In general, Front Panel Control has the highest priority and can override other control schemes.
  • Page 47: Energy Pulse Outputs

    4.1.3 Energy Pulse Outputs The PMC-53A-E comes standard with one Front Panel LED Pulse Output for energy pulsing and can be equipped with two optional Solid State Digital Outputs for kWh and kvarh pulsing, replacing the default Digital Outputs.
  • Page 48: Energy Measurements

    Demand is defined as the average power consumption over a fixed interval (usually 15 minutes) based on the Sliding Window method. The PMC-53A-E provides Present Demand and Predicted Demand for Ia, Ib, Ic, kW Total, kvar Total and kVA Total, updated once a second, as well as Max Demand for Ia, Ib, Ic, kW Total, kvar Total and kVA Total of TOU Tariff 1 to 8 in This Month (Since Last Reset) and Last Month (Before Last Reset).
  • Page 49: Power Quality

    I1, I2 are the Positive and Negative Sequence Components for Current, respectively. 4.3.3 Harmonics The PMC-53A-E provides Voltage and Current with THD, TOHD, TEHD and up to the 31 individual harmonics analysis. Additionally, TDD, K-Factor, and Crest Factor for Current are provided as well. All harmonic parameters are available via the Front Panel or through communications.
  • Page 50 CET Electric Technology THDf: ∞ √∑ THDf = ×100% THDr: ∞ √∑ THDr = ×100% ∞ √∑ where I represents the RMS value of the fundamental component, and I represents the RMS value for the n harmonic. 4.3.3.2 TDD Total Demand Distortion (TDD) is defined as the ratio of the RMS of the Harmonic Current to the RMS of the Rated or Maximum Fundamental Current Demand.

    4.5 Logging 4.5.1 Max/Min Log The PMC-53A-E records the Max Log and Min Log of This Month (Since Last Reset) and Last Month (Before Last Reset) with timestamp for 45 parameters. Each log includes the relevant parameter value and its timestamp. The recorded data is stored in the device’s non-volatile memory and will not suffer any loss in the event of a power failure.
  • Page 54: Peak Demand Log

    When the wiring mode is 1P3W, the demand measurements for Phase C are invalid. 4.5.3 Monthly Energy Log The PMC-53A-E stores monthly energy data for the present month and the last 12 months. The Monthly Energy Log Self-read Time setup parameter allows the user to specify the time and day of the month for the Recorder’s Self-read operation via communications.
  • Page 55: Daily And Monthly Freeze Log

    The PMC-53A-E’s 4MB log memory is divided equally into 5 buffers of 800kB each. By default, each DR is allocated one 800kB buffer, which can hold a maximum ~118 days of recording with 16 parameters at 15-minute interval.
  • Page 56: Time Of Use (Tou)

    TOU is used for electricity pricing that varies depending on the time of day, day of week, and season. The TOU system allows the user to configure an electricity price schedule inside the PMC-53A-E and accumulate energy consumption into different TOU tariffs based on the time of consumption. TOU programming is only supported through communications.
  • Page 57: Communications

     8 Tariffs Instead of using the TOU schedule to switch between Tariffs, the PMC-53A-E supports Tariff switching based on the status of DI1 to DI3. The 3 Digital Inputs (DI1, DI2 and DI3) represent 3 binary digits where Tariff 1=000, Tariff 2=001, Tariff 3= 010, …, Tariff 7=110 and Tariff 8=111 where DI1 represents the least significant digit and DI3...
