This Practice provides fabrication details and describes the minimum requirements for assembling field junction boxes used for instrument connections.
This guide applies to surge-protective devices (SPDs) intended for connection to 50 Hz to 60 Hz ac power circuits rated 1000 V RMS or less. This guide describes the effects on SPDs of power system disturbances occurring in these low-voltage ac power circuits. The disturbances are not limited to...
These guidelines for bolted flange joint assemblies (BFJAs) apply principally to pressure-boundary flanged joints with ring-type gaskets that are entirely within the circle enclosed by the bolt holes and with no contact outside this circle.1 These guidelines may be selectively applied to other...
This Practice provides guidance for the application of instrumentation to monitor rotating equipment for machinery protection, enhanced performance, and predictive maintenance. This Practice describes the following: a. Typical applications for continuous on-line monitoring of rotating equipment b....
This Practice provides requirements criteria for level measurement equipment selection and for the design of level measurement systems. This Practice describes the design requirements for differential pressure, radar, ultrasonic, displacement, capacitance, nuclear level measurement systems and...
This standard covers the design, testing, and installation of metal-enclosed switchgear that incorporates gas (typically SF6) at higher than ambient pressure as an insulation medium for alternating-current applications rated above 1 kV to 52 kV. Contents of switchgear may include but are not...
This Standard provides methods for repair of equipment, piping, pipelines, and associated ancillary equipment within the scope of ASME Pressure Technology Codes and Standards1 after they have been placed in service. These repair methods include relevant design, fabrication, examination, and testing...
This standard specifies the requirements of Phasor Data Concentrators (PDCs) for power systems. It includes requirements for: a) Data aggregation b) Processing of synchrophasors and other synchronized data c) Data interfaces with other systems d) Handling of commands, configuration, and other...
This standard is intended to define the requirements for current transformers with a maximum of secondary output of 250 milliamperes. These requirements of ratios, Accuracy classes, burdens and test methods supplement but are not subordinate to IEEE C57.13™ Standard Requirements for Instrument...
This Practice provides guidelines for selecting instrumentation used in hygienic process applications such as food and pharmaceutical facilities. This Practice includes all types of hygienic instrumentation. Non-hygienic instrumentation is not covered (e.g., black and gray utilities). PURPOSE AND...
This Guide provides protection methods for different types of Phase Shifting Transformers (PST) and discusses the interaction between protection and operating conditions of PSTs. Models representing PSTs to determine short circuit currents for relaying functions are presented. Sizing and location...
This guide is applicable to the methods of Dielectric Frequency Response (DFR) of liquid immersed transformers. The guide includes recommendations for instrumentation, procedures for performing the tests, and techniques for analyzing the data. This guide can be used in both field and factory...
This standard applies to the avalanche breakdown diodes 1 used for surge protection on systems with voltages equal to or less than 1000 V rms or 1200 V dc. The avalanche breakdown diode surge suppressor is a semiconductor diode which can operate in either the forward or reverse direction of its V-I...
This Practice describes the requirements for selection of pressure regulators including applications, sizing, construction, pressure protection, materials of construction, installation, and noise.
