Transmission Line Pulse Testing
-
Transmission Line Pulse testing, or TLP testing, is a method for semiconductor characterization of Electrostatic Discharge (ESD) protection structures. In the Transmission Line Pulse test, high current pulses are applied to the pin under test (PUT) at successively higher levels through a coaxial cable of specified length. The applied pulses are of a current amplitude and duration representative of the Human Body Model (HBM) event (or a Charged Device Model – CDM – event in the case of Very Fast TLP, or VF-TLP).

LV Iron Core Line & Load Reactors
-
Line and load reactors are generally serial-connected to the input and/or output terminals of three phase equipment such as motor speed controllers, inverters and UPS systems. These equipment make use of semiconductor switches such as IGBTs, thyristors, and diodes and therefore create harmonic distortion and high switching over-voltages (dv/dt). Use of such equipment has been becoming more widespread as the technology advances. However, the negative effects of these equipment should not be overlooked.
