Much of thechange is due to the European Union (EU) Directives regarding theseissues. Not only has thedensity of the electronic assembly increased, but many changes aretaking place throughout the entire supply chain regarding the use ofhazardous materials and the requirements for recycling.

A separate terminal block is provided which is coupled through a multi-lead connector to the meter circuit and which provides discrete individual terminal outputs readily wired by utility personnel trained in the use of older mechanical metering systems.A publication of the Surface Mount Technology AssociationJournal ofSurface MountTechnologyApril-June 2013 Volume 26, Issue 2Free Tutorial for Members atSMTA InternationalOctober 17, 2013Fort Worth, TexasOn Thursday, October 17, Cheryl Tulkoff, DfR Solutions, will present“Design for Reliability for PCBs“ at no charge to SMTA membersduring SMTA International in Fort Worth, Texas.Designing printed boards today is more difficult than ever beforebecause of the increased lead free process temperature requirementsand associated changes required in manufacturing. These surfaces cooperate with spring biased contacts arranged to achieve proper contact with them when the meter cover is rotated into its latched orientation. Further, a key actuated switching input is provided through the cover face of the meter with the use of a pattern of contact surfaces positioned on the inner surface of the face. The meter structure is provided an EMF and RF barrier coupled to through the interconnection of the meter cover to neutral reference. Volt amperes are computed with respect to the zero cross-over events for both voltage and current samples, while quantities such as Q and var are developed by selective delayed multiplication of the unit degree samples.Ībstract: Metering apparatus which employs a structure conforming to long accepted industrial standards but which is adapted to meet the requirements for highly versatile solid-state meter circuits having a multitude of outputs both in terms of electrical signals and visual display. Generally, six of these outputs will be elected by the user. These expanded data valuations for current and voltage then are selectively multiplied for each degree sampled to develop data available for generation of 12 electrical parameter outputs.

The scaling factor and the range data then are multipled to develop a digital representation of the sample amplitude which may have as many as 21 significant bits plus a sign bit. Sampling commences with a zero cross-over and a first digital conversion provides range data for developing scaling factors which are retained in memory and for providing a selective gain for amplifying. Abstract: Method and apparatus for metering polyphase power sources in which cycles for each phase are sampled at each degree and converted to a binary representation of amplitude.
