Differential Voltage Probe Applications

High voltage transmission is often thought of when thinking of high voltage applications, however there are many applications that require a high voltage power source. The definition for high voltage applications varies by industry and region. The IEC defines high voltage as anything above 1kV for AC and above 1.5kV for DC, in automotive engineering high voltage is anything above 60V. The primary use of high voltage outside of transmission can be found in the industrial, scientific, medical and imaging fields.

High voltage applications within the medical field include:-
Electrophoresis (a technique used to separate proteins, and nucleic acids such as DNA/RNA based on their size and electrical charge)
PCR (polymerase chain reaction) tests, and DNA sequencing
X-ray tubes require a high voltage to be able to generate x-rays used for imaging
Image intensifiers (where photomultiplier tubes also use a high voltage field to accelerate photoelectrons, causing them to collide with the dynodes inside the tube and release more electrons. This effectively multiplies the incoming light signal and is used for detection of weak signals

HV applications outside the medical field:-
High voltage testing of wires and insulations
Electrostatic screening
Electrostatic chucks used in semiconductor manufacture
Electrostatic flocking (electric charge to orient fibres through an electric field)
Electrostatic force (some air filters and requires a high voltage power source to operate)
Particle accelerators using multiple pulsed power stages to accelerate electrons, causing high energy collisions
High voltage power supplies
High voltage fields used to change the direction of charged particles, electron beam technologies
Electron lithography
Electron beam welding and electron beam sputtering
Display Technologies using compact high voltage power supplies
X-ray applications, pulse generators, electron beams
Laser where a pulsed power source controls the lamp
