battery boxes Testing Equipment

All plastic mouldings - including battery boxes - can be checked for defects by using high-voltage AC or DC testing methods.

The principle is simple; electrical potential is supplied to an electrode (such as our drum-brush electrode) which is swept over the internal test area of the battery box. Conductive material (such as a steel plate) is placed against the outside of the battery box and faults can be identified where a spark arcs through them to earth from the electrode. 

Provided the test voltage is within the limit of the test material's dielectric strength, any sparks created identify the location of a fault and potential leak/weakness.

Battery boxes can be tested for faults by placing the box on a metal plate. By applying a test voltage to an electrode inside the box, the moulding can be checked thoroughly - particularly at the injection points - and any faults found. Defects will be identified by a spark passing from the electrode, through the defect itself, to earth (the conductive material placed outside the battery box.

A battery-powered holiday detector can be used to perform these tests manually or our mains-powered DCCT is more suitable if the process is to be automated into a production line. AC Spark Testers - such as our ST-AC Pro' or PST-100 can be used when higher test voltages are required.
