Overview
HD 384.4.45 S1:1989 (aligned with IEC 60364-4-45:1984) addresses protection against undervoltage in electrical installations of buildings. The standard covers precautions to take where a drop in voltage, or a loss and subsequent restoration of voltage, could create dangerous situations for persons or property, or where parts of the installation or connected equipment may be damaged by voltage reduction.
This chapter is part of the broader HD 384 series on protection for safety and forms guidance for designers, installers and safety assessors responsible for building electrical systems and supply continuity.
Key Topics
- Scope and risk assessment: identifying circuits, equipment and locations where undervoltage or voltage restoration can cause hazards or equipment damage.
- Detection and monitoring: use of voltage monitoring and detection measures to identify drops or interruptions in supply.
- Protection measures: principles for implementing protective devices and strategies to prevent unsafe conditions when voltage falls below acceptable levels.
- Coordination with supply systems: considerations where supply characteristics or system faults may cause undervoltage across part or all of an installation.
- Restoration management: precautions for safe restoration of voltage after an interruption to avoid dangerous or damaging transients.
Practical keywords: undervoltage protection, voltage drop, electrical safety, building installations, supply monitoring, protective devices.
Applications
The guidance in HD 384.4.45 S1:1989 is relevant where undervoltage can affect safety or equipment integrity, including:
- Emergency and life‑safety systems (lighting, alarms)
- Medical and laboratory equipment sensitive to voltage variations
- Industrial control systems and motors vulnerable to undervoltage
- Data centers and communication equipment requiring stable supply
- Lifts, access control and security systems where unexpected restart or loss of function could create hazards
Common practical measures derived from the standard include installing voltage monitoring relays, alarm systems for loss or restoration of supply, coordinated protective schemes at distribution points, and use of alternative power sources (e.g., UPS, emergency supplies) where continuity is critical.
