Chroma 11210 battery cell insulation tester is an instrument used for accurately measuring leakage current (LC) and insulation resistance (IR) of battery jelly-roll/dry-cell as well as various insulation materials. In addition to standard LC/IR measurement, the 11210 has a unique function that detects partial discharge (PD) or flashover that may have occurred inside the insulation material during the high voltage insulation testing process. With PD detection of the battery's internal status before electrolyte filling, defective products can be filtered out before entering the next stage of production preventing the potential hazards that may occur in the field. In contrast to traditional methods of insulation test, Chroma 11210 provides an entirely new concept for inspection and evaluation of battery quality.
PD Detection and Measurement Function
Chroma 11210 battery cell insulation tester detects any PD or flashover that may occur inside the battery cells. There are two phases of detection that the 11210 employs with different circuitries used. The first phase is in CC (Constant Current) mode when the 11210 charges the DUT with a constant current set by the user. During this mode, the 11210 will monitor the voltage level and its slope. Any glitches on the voltage slope or any unexpected changes of the slope will be detected by the 11210 and reported as PD occurrences.
The second phase is in CV (Constant Voltage) mode. In this mode, only a stable leakage current should exist. Thus any unusual and protruding pulses on the current waveform are typically the result of an abnormal discharge (i.e. PD or flashover) which will also be detected and reported by the 11210 as a PD occurrence. Chroma 11210 not only detects, but also roughly measures the magnitude of the PD pulses during these modes.
Capacitor Test Applications with 11210
Chroma 11210 is the next generation and advanced version of its predecessor the Chroma 11200 capacitor LC/IR meter. The 11210 includes more versatile functions with higher accuracy, however, retains all the major functions and capabilities found in the 11200. Therefore, the 11210 is also an advanced LC/IR meter for all types of capacitors. In the production line, the 11210 is able to test capacitors at a very high speed (~20ms per DUT) with appropriate fixtures.
