TRACKING INDEX TEST APPARATUS (IEC 60112).
IEC 60112 – Method for determining the comparative and the proof tracking index of solid insulating materials under moist conditions.
The TRACKING INDEX APPARATUS from Se.com is designed and manufactured to perform the test specified in many standards ( IEC 60335, IEC 60065, IEC 60745, IEC 61029 ) to determine compliance whit safety requirements related to solid insulating materials under moist conditions.
The TRACKING INDEX APPARATUS from Se.com is designed to
determining
the Comparative tracking Index (CTI). The TRACKING INDEX APPARATUS from Se.com is totally controlled by PC (Embedded PC) with drop indication, voltage indication, current indication and timmer indication on a 15” digital display LCD
Its is designed to meet the requirements of international safety regulatory agencies such as UL, DNV, IMQ, BVSQ, ITS, IRAM , CSA, VDE, DIN , INMETRO.
This method simulate tracking currents on insulation material by providing drops between electrodes. During normal use insulating material may be exposed to moisture and dirt that, if conductive, may cause stress and fire hazard.
The sample to be tested is subjected to a voltage between 0 to 600 Vac by means of two electrodes resting on it with a load of 1 Newton. Between electrodes, drops of conductive solution are dropped at regular intervals.
A pump feeds electrolyte through a nozzle to produce drops which fall on the sample.
The number of drops allowed to fall on the sample are preset by drop counter.
Sensing of a drop stops the pump until the next timing signal is received. Automatic shutdown is achieved when the tracking current exceeds 0,5 A , registering a FAIL. After the present number of drops and no breakdown, the unit will revert to standby mode and indicate a O.K.
