electrical safety test equipment, environment test equipment, test probes, go not go gauges

Some customers have questions on the probes with thruster and without thruster, herein we just talk about the difference.   Generally, the probes are applied to simulate the human’s finger, hand, tools and etc. to access to hazardous parts or live parts. In the test requirements to prevent access to hazardous parts, the probes should be applied appropriately force, the force is recommended by relative standards. The probes built-in thruster make it more convenient to use when force must be applied, and the probe without thruster must work with a force gauge to apply the force.   Both the probes with thruster or without thruster can pass the calibration from third-party lab authorized by ISO17025, users can choose the right one as per their needs.Normally, probes without thruster will only calibrate the sizes according to standards it concerns, but with thruster, both size and force will be calibrated.  If you just in need of the probes, please contact Pego to get more det...

  High voltage tracking test apparatus and tracking index test apparatus are both test equipment used to test certain physical properties of insulating materials, but the physical properties tested by the two equipment are different, therefore, the test standard base on the two equipment are also different, the following are the main differences between the two equipment.   1.  Definition The high-voltage tracking tester is to simulate the power frequency (48Hz-62Hz), using liquid pollutants and inclined specimen to evaluate the resistance to tracking and corrosion of electrical insulating materials under severe ambient conditions. The electrical tracking refers to the continuous deterioration of the solid insulating surface due to the discharge of a local area and the formation of conductive or partial conductive channels.   The tracking index test apparatus is to simulate the conductive substances deposited on the surface of insulating material caused by diffe...

UL746A High Current ARC Ignition Test Apparatus 32.5A/COSφ0.5   1.  Introduction: The high current arc ignition tes t apparatus is designed according to  IEC60950-1:2001  clause 4.7.3.6 , BS/EN60950-1:2001, BS7002:2001, GB4943-2001 and UL746A, IEC60947.1:1999, GB/T14048.1-2000, IEC730.1:1993, GB14536.1-1998 and etc..  It ’ s used to measure and assess  solid insulating material against to resistance to ignition from arcing electrical sources. A power 240V(AC)/60Hz is to be supplied to the test electrodes  (fixed electrode and movable electrode) , a series (inductive-resistive) air core impedance is to be provided to yield a short circuit current of 32.5A and a power factor of 0. 5. The sample is be to positioned with the electrodes making initial contact on the surface of the sample, the circuit is to be energized and the cyclic arcing started. The timing of arcs is to be adjusted to a rate of 40 arcs/min, the rate of electrode separation is to be 254±...

IEC60335-2-9 Low Carbon Steel Vessels for Testing Induction Hotplates  1.  Introduction The low carbon steel vessels are designed according to IEC60335-2-9:2002 figure 104, IEC60335-2-6 Fig. 102 , GB4706.14-2008 figure 10 and GB4706.22-2008 figure 102, they are applied to test the induction hotplates. The vessels are made of low carbon steel having a maximum carbon content of 0.08%, and the surface is sprayed with high temperature non-stick coating.  It is cylindrical without metallic handles or protrusions. The diameter of the flat area of the base of the vessel shall  be at least the diameter of the cooking zone. The base of the vessel shall not be convex. The concavity of the base of the vessel shall not exceed 0.6% of its diameter at the ambient temperature (20±5) ℃. 2.  Parameter Diameter of Cooking Zone (mm) Dimension d (mm) e (mm) a (mm) c (mm) ≤110 110 140 2±0.5 <0.006  d ＞110≤145 145 140 2±0.5 <0.006  d ＞145≤180 180 140 2±0.5 <0.006 ...
