Full title and description
Live working - Voltage detectors - Part 5: Voltage detecting systems (VDS). This international standard specifies requirements, tests and performance criteria for single‑pole voltage detecting systems that are capacitively coupled to live parts, used to detect the presence or absence of operating a.c. voltages on electrical systems.
Abstract
IEC 61243-5:1997 defines the design, construction and verification tests for voltage detecting systems (VDS) — including separable and integrated voltage indicators and phase comparators — intended for live‑working voltage detection over a defined voltage and frequency range. The standard covers functional requirements such as threshold voltage and input impedance, dielectric strength, climatic and vibration tests, response time, perceptibility of visual and audible indications, maintenance and interface dimensions for separable systems.

Scope
This part of IEC 61243 is applicable to single‑pole voltage detecting systems that are capacitively coupled to live parts and is intended for use on a.c. electrical systems with operating voltages from 1 kV up to 52 kV and for frequencies from 16 2/3 Hz to 60 Hz. The standard also applies to phase comparators intended to work with such VDS. It excludes fundamentally different detection principles (for example purely optical or resistive coupling) unless their performance is equivalent and the manufacturer states conformity where applicable.
Key topics and requirements
- Operational voltage and frequency range: 1 kV to 52 kV (AC) and 16 2/3 Hz to 60 Hz; application primarily to phase‑to‑phase systems and appropriate phase/earth conversions where needed.
- Types covered: separable (portable indicator + fixed coupling system) and integrated VDS (single unit with test point), including phase comparators.
- Performance criteria: threshold (sensitivity) and input impedance, response time, non‑response to DC, dielectric strength, and maintenance of indication until supply exhaustion.
- Environmental and mechanical tests: climatic (damp heat, temperature change), vibration, impact, salt mist and other IEC environmental tests appropriate to live‑working equipment.
- Human factors and signaling: clear and unambiguous visual and/or audible indication requirements, perceptibility criteria and phase‑rotation indication for comparators.
- Interface and mechanical requirements for separable systems: defined interface dimensions, coupling electrode connections and test point characteristics.
Typical use and users
Used by electrical utilities, high‑voltage maintenance crews, manufacturers of voltage detection and live‑working equipment, testing laboratories, and safety engineers responsible for live‑working procedures and verification that circuits are de‑energized. The standard is issued by IEC technical committee TC 78 (Live working), reflecting its primary audience in live‑working safety and HV operations.
Related standards
IEC 61243‑5:1997 has been withdrawn and is replaced by newer IEC standards addressing similar equipment and testing: notably IEC 62271‑213:2021 and IEC 62271‑215:2021 (which supersede and incorporate updated requirements for voltage detection and related live‑working apparatus). It is also related to other parts of the IEC 61243 series (voltage detectors) and to IEC standards on environmental and high‑voltage test techniques referenced within its normative annexes.
