Voltage Detecting and Indicating according IEC 62271-213:2021

International Electrotechnical Commission (IEC) has published new standard for Voltage Detecting Systems in 2021: IEC 62271-213:2021. This new standard has replaced the old standard IEC 61243-5 which was published in 1997 and the first edition of IEC 62271-206. It practically includes the combination of the contents of two standards IEC 61243-5 and IEC 62271-206 with certain differences and enhancements in the technical and physical aspects.

It presents the new definition of the voltage detection system. We can take a closer look at the definitions of the voltage detection systems as per the standards they apply below.

Application range
This part of IEC 62271 is applicable to the voltage detecting and indicating system (VDIS) to be installed on indoor and outdoor high-voltage equipment. This part of IEC 61243 is applicable to voltage detecting systems (VDS) This part of IEC 62271 is applicable to voltage presence indicating systems (VPIS) incorporated in a.c. switchgear and control gear covered by IEC 62271-200 or IEC 62271-201.
The VDIS as defined by this document includes a coupling system per phase (capacitive, resistive coupling or other technology) to connect to live parts (main circuit). VDS it's mean that are single-pole and are capacitively coupled to live parts. Voltage presence indicating systems are devices used to provide information to operators about the voltage condition of the main circuit of the switchgear in which they are installed.
The VDIS is applicable on systems with nominal voltages above 1 kV and service frequencies from 16,7 Hz up to and including 60 Hz. They are used to detect the presence or absence of operating voltage on a.c. electrical systems for voltages from 1 kV to 52 kV, and for frequencies from 16,7 Hz to 60 Hz. The indication of VPIS alone is not sufficient to prove that the system is dead: if operating procedures make it mandatory, relevant voltage detectors according to IEC 61243-1, IEC 61243-2 and IEC 61243-5 should be used.
The VDIS is used to detect and indicate the presence or absence of operating voltage. Voltage Detecting System (VDS): Devices used to detect the presence or absence of operating voltage.
It is not intended to distinguish between voltage not present (i.e. U < 10 % of nominal voltage) and dead circuit state (i.e. U = 0 V).


  • VPIS is Voltage Presence Indicator System. If the indicator lamp doesn’t ON, it’s not necessarily that there’s no voltage (maybe the lamp has burned out).
  • VDS is Voltage Detecting System, it doesn’t include indicator lamp. Instead, it can output the signal voltage through a port on the front device. User must check voltage with Voltmeter
  • VDIS Is a combination of the two standards above, including display by indicator lamp or LCD and must have an additional port to measure voltage signals on the front device.
