SAE J1301_201702

Truck Deformation Classification

Published by: 2017-02-23 / 2017-02-23

The scope and purpose of this SAE Recommended Practice is to provide a classification system for deformation sustained by trucks involved in collisions on the highway. Application of the document is limited to medium trucks, heavy trucks, and articulated combinations.

The TDC classifies collision contact deformation, as opposed to induced deformation, so that the deformation is segregated into rather narrow limits or categories. Studies of collision deformation can then be performed on one or many data banks with assurance that data under study are of essentially the same type.

Many of the features of the SAE J224 MAR80 have been retained in this document, although the characters within specific columns vary. Each document must therefore be applied to the appropriate vehicle type. It is also important to note that the Truck Deformation Classification (TDC) does not identify specific vehicle configurations and body types.

The TDC is an expression, useful to persons engaged in vehicle safety, to appropriately describe a collision-damaged truck with conciseness in oral and written communications. The TDC is also a research tool; however, it has not been designed for use in impact energy computation. The research community is cautioned not to attempt direct conversion calculations from the TDC to energy equivalents required to duplicate the damage.

The system consists of seven alphanumeric characters arranged in a specific order to form a descriptive composite of the vehicle damage (see Figure 1). The characters describe the principal force direction, location, specific area, type, and extent of damage.

The individual character positions are referenced by column number for identification. The definition of each classification is provided in subsequent sections.

IEEE Draft Standard Requirements for Liquid-Immersed Distribution Substation Transformers

Published by: / 39 pages

Scope

This standard covers certain electrical, dimensional, and mechanical characteristics of 50 Hz and 60 Hz, two winding, liquid-immersed distribution substation transformers. Such transformers may be remotely or integrally associated with either primary and secondary switchgear or substations, or both, for step-down or step-up purposes rated as follows:a) 112.5 kVA through 10 000 kVA three-phaseb) 250 kVA through 6667 kVA single-phasec) High voltage 69 000 V and below and low voltage 34 500 V and belowIt is not intended that this standard shall apply to dry-type, regulating, pad-mounted, secondary-network,furnace, rectifier, mobile, railway, or mine transformers.

Abstract

Revision Standard – Unapproved Draft.

Small power transformers have become a significant element in distribution systems supplying large commercial customers like major resort hotels and site-specific industrial customers that desire the local utility to own, operate, and maintain the serving transformer. These transformers can range in sizes from 112.5 kVA to 10 000 kVA with primary voltages at 69 000 V and below and secondary voltages from 34 500 V to 120 V. Transformers in this standard are generally for larger distribution customers often with special voltages or installation requirements like convention centers with large chiller plants and extensive exhibit space. There is often a desire to serve these transformers from underground systems using side-mounted bushings on the primary. This standard seeks to define the small power transformer that is applied as more than just a limited scope version of the power transformers covered by IEEE Std C57.12.10TM and as more than a large distribution class transformer covered by IEEE Std C57.12.34TM.

IEEE PC57.119

IEEE Draft Recommended Practice for Performing Temperature Rise Tests on Liquid-Immersed Power Transformers at Loads Beyond Nameplate Ratings

Published by: / 49 pages

Scope

This recommended practice covers temperature rise test procedures for determining those thermal characteristics of power transformers needed to appraise the transformer’s load carrying capabilities at specic loading conditions other than rated load.

Purpose

These recommended test procedures for performing temperature rise tests on power transformers are for the purpose ofa) Determining the thermal characteristics of a transformer needed to appraise the thermal performance of a transformer at loads other than nameplate ratingb) Verifying that a transformer can be loaded with a specified load profile without exceeding specied temperature rise c) Assessing a transformer’s performance during transient loading, simulating a load cycle that includes loads in excess of nameplate ratingTests performed in accordance with Clause 9 are for the purpose of determining transformer thermal characteristics in a consistent manner. Data may then be accumulated from a large number of transformers and used to evaluate the accuracy of the equations and the empirical constants used in the loading guides.Tests performed in accordance with Clause 10 are for the purpose of demonstrating the thermal effects of loading a transformer with a specified sequence of loads, including loads beyond nameplate rating.Tests performed in accordance with Clause 11 are for the combined purposes of determining the thermal characteristics of a transformer and demonstrating the thermal effects of loading with a designated load cycle. This is accomplished by performing temperature rise tests at three loads, similar to Clause 9, except the three loads are selected to simulate the thermal effects of a specific load cycle.It is not intended that all of these procedures be performed on a transformer design. It is intended that only one of the following combination of test procedures be specified:a) Clause 9 only, when thermal characteristics are to be determined.b) Clause 10 only, when only verifi;cation of complying with temperatures limits when loaded to a specific load profile is needed.c) Clause 9 plus Clause 10, when both thermal characteristics and verification of compliance with temperature limits when loaded to a specific load profile are needed.d) Clause 11 when both thermal characteristics and verification of compliance with temperature limits when loaded to a specific load profile are required, and the load profile can be represented with three steady state loads.The user should specify which of the test procedures are required at the time of specification.A further purpose of these procedures is to obtain information with respect to possible loading limitations imposed on the transformer by oil levels and ancillary equipment when the transformer is operated at loads beyond nameplate rating.

Abstract

Revision Standard – Unapproved Draft.

Recommendations are made, where possible, regarding the performance and evaluation of temperature rise tests on liquid-immersed power transformers beyond nameplate ratings. The intent is to assist power transformer manufacturers, and the ultimate users, in evaluating thermal performance of the transformers under varying loads.
