35kv capacitor wiring

What is a pole mounted capacitor bank?

Pole Mounted Capacitor Banks provide power factor correction and voltage control on medium voltage industrial and utility electrical overhead systems. Banks are available in configurations rated up to 4500kVAr at voltages up to 35kV (grounded wye). “Polemounts” are available as a fixed or switched system depending on system profile.

What is a 15 kV circuit?

The most common 15-kV voltage is 12.47 kV, which has a line-to-ground voltage of 7.2 kV. The dividing line between distribution and subtransmission is often gray. Some lines act as both subtransmission and distribution circuits. A 34.5-kV circuit may feed a few 12.5-kV distribution substations, but it may also serve some load directly.

What voltage is a 15 kV insulator suitable for?

For example, a 15-kV insulator is suitable for application on any 15-kV class voltage, including 12.47 kV, 13.2 kV, and 13.8 kV. Cables, terminations, insulators, bushings, reclosers, and cutouts all have a voltage class rating.

How do you ground a capacitor?

Ground the end of the cable shield in the capacitor yard to a ‘peninsula’ grounding system. Ground the cable shield to the ground grid at the nearest manhole, hand hole, trench, or tunnel adjacent to the capacitors. Ground the shield at the entrance to the control or relay house.

How to choose a battery cable conductor?

The battery cable conductors should be selected so that the voltage drop from the battery terminals to the utilization equipment, for the expected load current, does not result in a voltage below the minimum voltage rating of the utilization equipment. A designer should consider using end of discharge voltage for critical circuits.

What kV is a distribution voltage?

Most distribution voltages are between 4 and 35 kV. In this article, unless otherwise specified, voltages are given as line-to-line voltages; this follows normal industry practice, but it is sometimes a source of confusion. The four major voltage classes are 5, 15, 25, and 35 kV.
