HIGH VOLTAGE SOURCE: Rhumkorff’s Coil (Spark Coil), 12V DC
$ 774.00 excl. GST
• This High Voltage Source – Rhumkorff’s Coil (Spark Coil) apparatus demonstrates electrical and magnetic principles.
• The vibrating points are tungsten and a high quality capacitor is used to reduce arcing.
• A complete unit with removable and adjustable needle points and with insulated handles runs from about 6 to 9V DC producing a spark length of about 25-30mm long which is normal.
• To protect the primary winding a fuse is fitted and the secondary winding containing thousands of turns can be slid from the primary to reduce the coupling.
• Supervision is required.

(Wikipedia excerpt: ..."...A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.[1] Most HVDC links use voltages between 100 kV and 800 kV.
HVDC lines are commonly used for long-distance power transmission, since they require fewer conductors and incur less power loss than equivalent AC lines. HVDC also allows power transmission between AC transmission systems that are not synchronized. Since the power flow through an HVDC link can be controlled independently of the phase angle between source and load, it can stabilize a network against disturbances due to rapid changes in power. HVDC also allows the transfer of power between grid systems running at different frequencies, such as 50 and 60 Hz. This improves the stability and economy of each grid, by allowing the exchange of power between previously incompatible networks.....")
