What are the characteristics of HV ceramic disc capacitors?

Coupling, by-passing high frequency circuits also use HV ceramic disc capacitors. - a high internal resistance. - a high dielectric strength. - low or moderate losses at working frequencies (from 50 Hz up to 10 kHz). The active power (or losses) being: Wa = 2 FC tg V2 = k (C tg ) (F V2)

What is a high voltage ceramic capacitor?

HIGH VOLTAGE CERAMIC CAPACITORSare particularly suitable for applications requiring a high voltage (from 10 to 150 kV), while reactive current remains low. Ceramic capacitors also achieve very good performance under pulse and discharge conditions. Various disc types cover a wide range of capacitances and voltages as shown in the following figure.

What is a ceramic disc capacitor used for?

(50 & 60Hz) Uncoated discs without fixtures The main applications include live line indicators, AC dividers, grading systems for power distribution network, protection for HV switches and power circuit breakers. Coupling, by-passing high frequency circuits also use HV ceramic disc capacitors. - a high internal resistance.

What is the temperature coefficient of a high voltage ceramic capacitor?

C • Temperature coefficient TC = +100 to -750 ppm/°C depending on capacitance value • Tolerances and associated ±1pF (F) ±10% (K) ±20% (M) series C < 10pF E 12 E 6 20TPC High Voltage Ceramic Capacitors Quality Assurance LOT RELEASE Every high voltage and power capacitor is inspected individually during manufacture.

Why do we use ceramic HV capacitors?

Coupling, by-passing high frequencies circuits where an important reactive power is needed also use ceramic HV capacitors. • These applications require: - a high internal resistance - a high dielectric strength together with: - low or moderate losses at working frequencies (from 50 Hz up to a few kHz).

What is a high and low voltage capacitor divider?

The high and low voltage elements can be supplied either separately or in the same molding. The capacitor divider ratio can be adjusted between 1/200 and 1/10 together with a tolerance that can be as tight as 2%. The products can be developed for rated line voltage from 10kV up to 150 KV rms.
