What is PD IEC/TR 62689-100- Current and voltage sensors or detectors about?
PD IEC/TR 62689-100 is a safety standard on current and voltage sensors or detectors.
PD IEC/TR 62689-100, which is a Technical Report, was prepared jointly with TC 57 with the scope to prepare requirements and proposals for the IEC 61850 series data model extensions to support fault passage indicators (all classes and extended functions) applications to be introduced in the future IEC 61850906 and that, in turn, will be needed for the preparation of the future IEC 62689-3.
A fault passage indicator (FPI) is a device that detects faults providing indications about their localization (upstream or downstream from the FPI’s location) and/or about the direction of fault current (usually referred to as the direction of load current, i.e., from the HV/MV transformer towards the end of MV feeders in a radial operated network).
Who is PD IEC/TR 62689-100- Current and voltage sensors or detectors for?
PD IEC/TR 62689-100 on current and voltage sensors or detectors is relevant to:
- Manufacturers of current and voltage sensors or detectors
- Manufacturers of fault passage indicators
- Electricians
- Electrical engineers
Why should you use PD IEC/TR 62689-100- Current and voltage sensors or detectors?
Fault passage indication (FtPInd) is the main purpose of proper devices indicated as Fault passage indicator (FPI) or distribution substation unit (DSU), depending on their performances, which are, respectively, a device or a device/combination of devices and/or functions able to detect faults and provide indications about their localization.
PD IEC/TR 62689-100 has two main framework constraints with editorial and technical impacts as:
- PD IEC/TR 62689-100 will be merged with IEC TR 61850-90-61: IEC TR 62689-100 will exactly stick with the targeted document structure and principles
- PD IEC/TR 62689-100 intends to prepare the content of the future IEC 62689-32 which will rely on the functional requirements expressed in IEC 62689-1 and IEC 62689-2
Overall, PD IEC/TR 62689-100 is beneficial as it helps users to detect the phase to earth fault on solidly earthed systems, it is required an overcurrent function and, if necessary, a confirmation based on voltage presence/absence or current absence.
