What is a low-voltage dry-type alternating current (AC) power capacitor?
This document provides standard requirements and general guidelines for the design, performance, testing and application of low-voltage dry-type alternating current (AC) power capacitors rated 1,000V or lower, and for connection to low-voltage distribution systems operating at a nominal frequency of 50Hz or 60Hz.
What are current standards for capacitors?
Current standards for capacitors are defined so that capacitors can withstand a permanent overcurrent of 30%. These standards also permit a maximum tolerance of 10% on the nominal capacitance. Cables must therefore the sized at least for: Icable = 1.3 × 1.1 (Inominal capacitor) i.e. Icable = 1.43 × Inominal
What are the requirements for a capacitor cell?
3.4 The capacitor cells shall be impregnated with a biodegradable, environmentally friendly and non-toxic dielectric fluid. 3.5 The capacitor cells shall be suitable for continuous operation over a temperature range of -400C to +700C. 3.6 The capacitor cells shall be of “low loss” design with losses not to exceed 0.5 watts per KVAR.
What are the requirements for a capacitor enclosure?
9.2 The structure of the capacitor enclosure shall be constructed of 11 gauge steel. 9.3 The capacitor enclosure shall be painted with ANSI 61 gray, acrylic urethane paint. 9.4 The enclosure shall be equipped with louvered side panels to provide cooling air intake. 9.5 The enclosure shall be front access with removable side and back panels.
What size capacitor should a cable be?
Go back to capacitors installation options ↑ Current standards for capacitors are defined so that capacitors can withstand a permanent overcurrent of 30%. These standards also permit a maximum tolerance of 10% on the nominal capacitance. Cables must therefore the sized at least for: Icable = 1.3 × 1.1 (Inominal capacitor)
