1 Scope
1.1 The requirements of this standard apply to off-board unidirectional and bidirectional equipment rated
1000 Vac and 1500 Vdc or less, that transfers electrical energy between an electric vehicle and off board
loads as well as operating in parallel with an electric power system, such as the electric utility grid, using a
permanently attached vehicle connector. Equipment that has…
High voltage direct current (HVDC) grid systems and connected converter stations - Guideline and par...
IEC TS 63291-2:2023 defines aspects on planning, specification, and execution of multi-vendor HVDC grid systems also referred to as HVDC grids. The terms "HVDC grid systems" or "HVDC grids" are used in this document to describe HVDC systems for power transmission having more than two HVDC stations connected to a common DC circuit. The DC circuit can be of radial or meshed…

Connectors for electrical and electronic equipment - Tests and measurements - Part 99-003: Endurance...
IEC 60512-99-003:2023 is used for the assessment of connectors within the scope of SC 48B that are used in balanced single-pair communication cabling with remote power, in support of e.g., IEEE 802.3 remote powering applications for point-to-point connections.
The object of this document is to detail a test schedule to determine the ability of sets of single-pair connectors as defined in the IEC…
Low voltage switchgear and controlgear - Partial discharge voltages and PD-level in low voltage swit...
IEC TR 63434:2023 is intended to provide awareness about partial discharge phenomena. This document gives guidance for some conditions when partial discharge can occur in low voltage switchgear and controlgear connected to networks of up to 1 000 V AC. Internal operational voltages can exceed these values. This document gives guidance on the design of conductors and dimensioning of insulation…
Electricity metering data exchange – The DLMS<em>®</em>/COSEM suite - Part 8-12: Communi...
IEC 62056-8-12:2023 describes the use of DLMS®/COSEM for Low-Power Wide Area Networks (LPWANs). It specifies how the COSEM data model and the DLMS®/COSEM application layer can be used over various LPWAN technologies using an adaptation layer based on IETF RFC 8724, and in particular over LoRaWAN.
This profile is intended to be used with LPWANs as defined in IETF RFC 8724, in particular LoRaWAN.…
Power installations exceeding 1 kV AC and 1,5 kV DC - Part 2: DC
IEC 61936-2:2023 provides, in a convenient form, requirements for the design and the erection of DC installations in systems with nominal voltages above 1,5 kV DC, so as to provide safety and proper functioning for the use intended.
For the purpose of interpreting this document, a DC installation is considered to be one of the following:
a) A converter station or DC switching station;
b) one (…
This document defines the general criteria for the development of flight-to-ground umbilical systems used by a space system. These criteria apply to the service arms or equivalent mechanisms, umbilical carriers and plates, couplings, connectors, withdrawal and retract devices, handling mechanisms and control systems for mechanisms, as well as the prevention of accidental cross-connection.
