The tracking is with the CTI value(Comparative Tracking Index) is determined and

with the PTI value (Proof Tracking Index) examined.The CTI value indicates to what

Voltage, the base material is not tracking shows, when 50 drops of a standardized

electrolyte liquid are dropped.

Measured on the surface of the specimen, with a drop every 30 seconds falls

between two platinum electrodes.The functional structure allows, by fine

Adjustment of test voltage, current limit,turn-off time, drop size number of dropsand

accurate tests make. The unit works fully automatic, the control is electronic. The

test voltage can be adjusted up to 1000 V.
