<p>The apparatus is adapted for metering electrical energy on a continuous basis, and also for separately metering the energy supplied during time intervals during the day when peak system loads are expected, so as to provide a basis for surcharges for energy consumed during those peak load intervals. The system includes input means (58, 34, 18) to receive pulses representative of electrical energy consumption, means (within 12) for detecting the beginning and the end of a peak time of use period, a first register (withing 12) for accumulating the total count of pulses received during the peak time of use period, a second register (within 12) for accumulating the total count of pulses received, and a display means (44) interconnected with the registers (at 18, 36, 42, 40, 46) and operable selectively for reading out and displaying the contents of either one of the registers.</p> |
