Premier Electrosystems
The typical use of high voltage testing is to confirm performance. The high voltage tests are included in type and routine tests to meet the required IS standards, quality and reliability. Some of them are insulation resistance tests, dielectric type tests, lightning and switching impulse tests, partial discharge measurement, etc. Premier's high voltage tester checks the insulation between line to earth, neutral to earth, primary to earth, secondary to earth and between primary & secondary.

Techimp HQ S.r.L
The Impulsive Test Synchronization Module (ITSM) is a device aimed at generating a digital synchronization signal, to use the PDBaseII system for impulsive voltage PD test. The digital synchronization signal generated by the ITSM, is synchronized with the voltage impulse of the impulsive source (voltage generator). The ITSM must be connected between the DIN channel of PDBaseII and the output of the synchronization sensor (e.g. capacitive coupler). The ITSM provides also a low voltage signal reproducing the impulsive voltage source.

ECG KOKUSAI Co., Ltd.
This equipment is a system which does several electric characteristic tests, such as Armature and Stator coils. It is a system which performs an automatic test and judge according to the set-up parameters, and anyone can perform quality test judgment easily by desorbing a work. Moreover, an impulse test is efficient and does the electric examination of the winding state by not destroying the item.It is inductance and Q which the damped oscillatory wave form generated in a transient phenomenon waveform, i.e., coil, and when there are number of turns difference in a coil, a core, the difference in the material, etc. can judge it simultaneously.That is, almost all characters required as a quality of winding can be inspected very much in a short time.
