摘要： According to the present disclosure, an Intelligent Electronic Device (IED) such as a digital relay or protection device for Substation or Distribution Automation is conceived in a modular way, comprising distinct modules dedicated to distinct tasks and having dedicated housings or casings, which modules are mechanically arranged on a common support and both visible and accessible from outside of the IED at all times. Modules for signal input (process interface modules comprising a number of input terminals and signal processing (process data handling modules for evaluating signals in view of an automated protection function or as a communication gateway) define the basis of a modular arrangement that is not delimited by any prefabricated cover or cabinet and that allows for a quasi-unlimited flexibility regarding the number of modules and an easy replacement or extension of individual modules.

摘要： The disclosure relates to a process of configuring a standalone self-supplied numeric controlled relay for providing phase and earth over current protection to electrical systems by accurate current measurement. The arrangement for current measurement with control algorithms is provided for power control by providing amplified and conditioned current for optimization between the current to power an electronic circuit and the fidelity of a measured current waveform so that they both are at the acceptable levels at the same time. This disclosure describes the current sensing and associated algorithm for power control in a truly self-powered relay.

摘要： A fully operational digital protective relay or Intelligent Electronic Device (IED) are provided for protecting electrical equipment of a power distribution system. The relay includes an input module, a processing module and an output module. Signals received from current transformers connected to the input module are evaluated by the processing module, and in reaction thereto, trip signals can be output to an actuator of a circuit breaker via the output module. A base Human Machine Interface (HMI) enables a user to enter operating parameters such as a delay time or nominal current to the processing module. Optionally, a further HMI may be attached to the protective relay and connected, via a suitable interface for data exchange, to the processing module for the purpose of displaying protection-related information to a user. This further HMI is both optional and detachable. For example, the further HMI can be repeatedly attached to and detached from the protection device. The detachable HMI provides for an increased flexibility in the use of the protective relay, as a user may adapt its interfacing capability by acquiring a detachable HMI of the type and at the time that best suits his evolving needs.

摘要： A coated metal plate is provided as a mechanical fastening device for a roof deck. The top side of the metal plate can have a coated layer, and the bottom side of the metal plate has an adhesive layer. The adhesive layer is covered by a film, which is removable and can be peeled off at the time of installation. The bottom side of the metal plate is attached to the roof deck by the adhesive layer, and a roofing membrane is heat welded to the coated top side of the metal plate. The disc shaped metal plate can have a hole in the center of the plate, and a fastening device such as a screw can extend through the hole and attach the metal plate to the roof deck for additional support.

摘要： A method for sealing joints formed by the intersection and/or overlap of roofing membranes is disclosed. The method comprises the steps of applying strips of double sided tape to roofing membranes so as to secure the membranes to one another and to fill voids created at the intersection of the membranes. Securing the membranes using double-sided tape creates a tight seal which prevents the seepage of water and debris into the joint. A roof joint patch kit is also disclosed which comprises a roll of roofing membrane and a plurality of double-sided tape strips.
