BS EN 61010-2-032:2012

What is BS EN 61010-2-032 - Safety requirements for current sensors about? 

BS EN 61010-2-032 is a standard that serves safety requirements for current sensors, ensuring protection against electric shocks and prevention of short-circuits. 

BS EN 61010-2-032 specifies safety requirements for hand-held and hand-manipulated current sensors. 

The current sensors covered in BS EN 61010-2-032 are used for measuring, detecting or injecting current, or indicating current waveforms on circuits without physically opening the current path of the circuit being measured. 

In BS EN 61010-2-032, the requirements for protection against hazards resulting from normal use and reasonably foreseeable misuse of measuring circuits are given in Clause 101. 

Who is BS EN 61010-2-032 - Safety requirements for current sensors for? 

BS EN 61010-2-032 on safety requirements for current sensors applies to: 

• Manufacturers of current sensors 
• Dealers and importers of current sensors 
• Testing houses and labs for current sensors 
• Safety assurance services 
• Electrical testing services 

Why should you use BS EN 61010-2-032 - Safety requirements for current sensors? 

Current sensors are used for measuring and detecting current waveforms on circuits. These include measurement circuits that are part of electrical test and measurement equipment or process control equipment. The existence of these current sensors and circuits in equipment requires additional protective means between the current sensor, the circuit and an operator. 

BS EN 61010-2-032 provides users guidance on the following types of current sensors: 

• Type A: a current sensor designed to be applied around or removed from UNINSULATED HAZARDOUS LIVE conductors. 
• Type B: a current sensor that has protection against short-circuits between wires or busbars during clamping but without defined HAND-HELD or hand-manipulated parts which provide protection against electric shock during clamping. 
• Type C: a current sensor without protection against short-circuits between wires or busbars during clamping. 
• Type D: a current sensor designed to be applied around or removed from insulated conductors or from limited-energy circuit conductors. 

BS EN 61010-2-032 provides users guidance on protection against electric shock, mechanical hazards, spread of fire, resistance to mechanical stresses, temperature limits, protection interlocks, risk assessment and more, ensuring safety and protection in electrical applications. 

With obedience and compliance to BS EN 61010-2-032, users can develop and design current sensors, ensuring risk reduction and prevention of hazards for stable operability, performance and longevity in electrical testing and measurement applications. 

What’s changed since the last update? 

BS EN 61010-2-032:2012 supersedes BS EN 61010-2-032:2002, which is now withdrawn. 

BS EN 61010-2-032:2012 includes several technical changes with respect to BS EN 61010-2-032:2002. These include: 

• A new Type D current sensor has been defined. 
• Requirements for markings of measuring circuit TERMINALS and JAWS have been modified 
• Requirements have been added for specialized measuring circuit TERMINALS 
• The pull test for endcaps of flexible current sensors has been revised 
• Requirements have been added for temperature limits and resistance to heat to prevent thermal hazards from eddy currents and high currents
