Hello all, I'm looking for any standards / decisions / interpretations, etc... that discuss the use of capacitors to ground in industrial, fixed, permanently connected equipment. We have a 3 phase, 400V product that requires a significant amount of capacitance to ground, and the use of available "Y" rated capacitors is burdensome in that it would take a lot of them. We're aware of leakage current issues, and are well within the 5% allowance (EN50091-1-1, which references EN60950 for most core requirements). We are using about 1.3-2uf from each phase to ground. UL and CSA both do not require "y" type capacitors in this class of product, I'm hoping there is a similar rationale in Europe.
Thank you in advance for any comments you may have, Barry Marks
