The APC08, running at 400 kHz, features a combined regulation of better than 3 percent over line, load and temperature; ripple and noise of 75 mV for outputs greater than 2.5 V and transient response of 500 microseconds maximum. Overvoltage, overcurrent and overtemperature protection are provid...
The AC120LTR is GDT 120V 5KA THROUGH HOLE, that includes 120V Voltage DC Spark Over Nom, they are designed to operate with a 2 Pole Gas Discharge Tube Type, Technology is shown on datasheet note for use in a Gas Discharge Tubes, that offers Series features such as AC, Peak Pulse Curre...
In case of a negative transient overvoltage event the built-in freewheeling diode thwarts common surge protection devices (SPD) as spark gaps or varistors. This leads to a destruction of DC/DC-converters. In this paper a categorization of the threatening overvoltage events is shown, risk ...
Statnett developed new towers for the HVDC line made using circular hollow steel profiles. In addition, all fittings were developed and full scale tested to be corona free at 20% above operating voltage, i.e. 630 kV DC. Spark gap strings for lightning protection of the cable have also been...
