High Voltage Capacitors Ceramic 10 – 40kVdc K2500 Dielectric

Morgan Electro Ceramics has long experience of the manufacture of ceramic capacitors for high-voltage dc and power frequency applications.

Test Facilities available in addition to the standard and power factor equipment include:

  • Power frequency testing, 50Hz, up to 250kV
  • Impulse testing up to 600kVpk
  • Partial discharge testing up to 120kV
  • DC testing up to 60kV

The materials used are mainly high-K Type 2 ceramics with dielectric constants from 1000 to 10,000. These materials show significant and non-linear changes in dielectric constant with temperature and voltage and also exhibit changes with time, compared to Type 1 material s.

Applications include

  • HF Coupling
  • Fast repetition pulse circuitry
  • TIG welding (arc initiation) where a low loss factor is required to achieve maximum kVA at high frequencies

In addition to the standard products, custom-made components can be supplied with different dimensions and electrical characteristics.
