ICAR 0.265 µF 50 Hz High Voltage Capacitor (Part No: 3/626/2002)

Overview

The ICAR 0.265 µF 50 Hz capacitor, part no. 3/626/2002, is a high-voltage AC capacitor manufactured by ICAR S.p.A., an Italian producer of power and power-factor-correction capacitors.

The part is associated with the insulation level 17.5 / 38 / 95 kV, i.e. the 17.5 kV voltage class with its power-frequency and lightning-impulse withstand levels. A manufacturer datasheet for this specific part number was not located, so construction details and rated reactive power must be confirmed from the capacitor nameplate before ordering.

Understanding the ICAR 0.265 µF 50 Hz Rating

The capacitance of 0.265 µF is small compared with power-factor-correction units, which are usually rated in tens or hundreds of microfarads at low voltage. In medium-voltage equipment, capacitances of this order are typically found in surge protection capacitors for motors, generators and switchgear, and in capacitive coupling or voltage-divider circuits. The exact role of part no. 3/626/2002 depends on the equipment in which it is installed, so the original drawing or nameplate should always be used to confirm it.

The reactive power and current of a capacitor follow from its capacitance, frequency and applied voltage:

• Capacitive reactance: X_C = 1 / (2πfC). At 50 Hz and 0.265 µF this is about 12 kΩ.
• Current: I = U / X_C. For example, at 10 kV across the capacitor the current would be about 0.83 A.
• Reactive power: Q = 2πfCU². At the same illustrative 10 kV this gives about 8.3 kvar.

These figures are worked examples to show the order of magnitude; they are not the rated values of this part. The rated voltage must be taken from the nameplate.

What the Insulation Level 17.5 / 38 / 95 kV Means

Insulation levels for medium-voltage equipment are written as three values according to IEC practice:

The 17.5 kV class is used on systems with nominal voltages such as 11 kV, 13.8 kV and 15 kV, which are common in industrial and utility networks in Oman and the GCC.

How a High-Voltage Capacitor Works

A high-voltage capacitor stores energy in the electric field between conducting electrodes separated by a dielectric. Modern power capacitors generally use metal foil or metallised film electrodes with polypropylene film dielectric, wound into elements that are connected in series and parallel inside a sealed housing. The construction of this specific ICAR part is not published, so it should be confirmed from the unit itself. Many high-voltage capacitors include internal discharge resistors that reduce the residual voltage after disconnection; their presence and discharge time must also be checked on the nameplate.

Installation & Safety Notes

• Isolate, earth and short-circuit the capacitor terminals before handling. A disconnected capacitor can hold a dangerous charge.
• Inspect the housing for bulging, leaks or cracked bushings, which indicate internal failure.
• Measure capacitance with a suitable bridge or capacitance meter and compare it with the nameplate value; a significant change suggests element failure.
• Tighten terminal connections to the torque given by the equipment manufacturer and keep bushings clean, especially in dusty or salty environments.
• Replace capacitors in protective circuits with parts of the same capacitance, voltage rating and insulation level, so that the protection behaviour of the equipment does not change.

Typical Applications in Oman & the GCC

Medium-voltage capacitors in the 17.5 kV class are found in motor and generator surge protection panels, switchgear in oil and gas facilities, water pumping stations, desalination plants and utility substations. High ambient temperatures and dust make periodic inspection particularly important in the region.

Ordering the ICAR 0.265 µF 50 Hz Capacitor

Seven Star LLC supplies ICAR capacitors across Oman and the GCC. To help us confirm the correct item, please provide the part number 3/626/2002, a clear photo of the nameplate showing rated voltage and insulation level, the dimensions and terminal arrangement of the existing unit, and the make and model of the equipment it is fitted to. Our team can help confirm the correct ordering code before a quotation is issued.

Storage of Spare Capacitors

Keep spare high-voltage capacitors in their original packaging, upright, in a dry and shaded store away from direct sunlight. Short-circuit the terminals with a suitable shorting link during storage and transport, and check the housing and bushings for damage before installation. Recording the receipt date and the measured capacitance makes it easier to compare the unit with its nameplate value when it is eventually fitted.
