The extremely high input impedance (10 giga-ohms) minimizes circuit loading, providing for accurate and trusted readings.
The energy storage devices will mainly be used to offer grid support through circuit loading relief.
That might trip the circuit breaker, depending upon the circuit loading, the dimmer circuitry and the breaker type, so the LED driver requires an in-rush current limiting device, and the "pairing" of the LED/driver and the dimmer that's selected.
The lack of information about the current transformers errors appears in such cases, when secondary circuit loading is higher then rated or lower then permissible loading of 25 % rated value or minimal loading of 1 VA.
Phase angle errors are positive and more evenly depend on current transformers secondary circuit loading in the whole primary current zone (Fig.
The correct selection of current transformers secondary circuit loading may be one of the means of energy metering accuracy enhancement and elimination of systematic errors.
Therefore it is necessary to know not only standard errors margins of current transformers, but also real errors' values for the appropriate secondary circuit loading provided in the standard, i.
The result is that the actual circuit loading conditions move the maximum power transfer point away from the 50 [ohm] design point causing the node A junction to perform suboptimally.
21] differences between a 50 [ohm] system and actual circuit loading conditions of a matching network (note the significant difference in the matching network bandwidth and insertion loss).
This method provides a good first-order skew approximation for common groups of I/O cells recognizing that actual signal propagation velocity will vary due to circuit loading characteristics.
This step will help to further reduce interconnect skew, and maximize setup and hold timing margins for clocking and control circuits with consideration for circuit loading.
