  • Measuring alternating current flowing through an electricity supply distribution unit
    Patent number: 8624583
    Abstract: An apparatus (100) adapted to measure Alternating Current flowing through an electricity supply distribution unit (204) having a plurality of distribution cables (202). The apparatus (100) includes a plurality of current measuring devices (102), each of the current measuring devices (102), in use, measuring current flowing through one of the distribution cables (202), at least some of the current measuring devices (102) being mounted on a rigid/semi-rigid body (104), and a device configured to store and/or transfer information representing current measured by at least one of the current measuring devices (102).

  • Assessing a parameter of cells in the batteries of uninterruptable power supplies
    Patent number: 6765388
    Abstract: A method and apparatus for measuring the electrical efficacy of one or more battery cells for use in an uninterruptable power supply are disclosed. The efficacy is determined by making use of the ripple current which flows in the battery cells when in use in the uninterruptable power supply. Simultaneous measurement, for example, of the ripple current and a corresponding voltage component enables the internal impedance of a battery cell to be determined, the impedance acting as an indicator of electrical efficacy.
