SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT FOR MEASUREMENT, CONTROL, AND LABORATORY USE - PART 2-032: PARTICULAR REQUIREMENTS FOR HAND-HELD AND HAND-MANIPULATED CURRENT SENSORS FOR ELECTRICAL TEST AND MEASUREMENT (IEC 61010-2-032:2002, IDT)
MS IEC 61010-2-032:2008
Status : Original
Format : PDF

1 Scope and object
This clause of part 1 is applicable, except as follows:
1.1 Scope
Replacement:
This International Standard applies to the HAND-HELD and hand-manipulated CURR ....Read more ENT SENSORS
described below. These CURRENT SENSORS are for use in the measurement of current without
physically opening the current path of the circuit being measured. They may be stand-alone
CURRENT SENSORS or accessories to other equipment.
CURRENT SENSORS require hand manipulation before or after a test or measurement, but do
not necessarily need to be HAND-HELD during the test or measurement.
Type A CURRENT SENSOR: a CURRENT SENSOR designed to be applied around or removed from
uninsulated HAZARDOUS LIVE conductors. Type A CURRENT SENSORS have defined HAND-HELD or
hand-manipulated parts providing protection against electric shock from the conductor being
measured, and also have protection against short-circuits between wires and busbars during
clamping.
Type B CURRENT SENSOR: a CURRENT SENSOR which has protection against a short-circuit
between wires or busbars during clamping but without defined HAND-HELD or handmanipulated
parts which provide protection against electric shock during clamping. Additional
protective means are necessary to avoid electric shock from HAZARDOUS LIVE conductors
which cannot be de-energised during application or removal of the CURRENT SENSOR.
NOTE Type B CURRENT SENSORS include flexible CURRENT SENSORS.
Type C CURRENT SENSOR: a CURRENT SENSOR without protection against short-circuits between
wires or busbars during clamping. Type C CURRENT SENSORS are intended to be applied to or
removed from uninsulated HAZARDOUS LIVE conductors only when they are de-energised.
NOTE Type C CURRENT SENSORS include some types of split-core transducers. Close
