Vitronics oven corner grounded delta?

Electronics Forum | Tue Nov 15 15:37:05 EST 2011 | comatose

I have a new (to me) Vitronics XPM3 oven which we're hooking up. It requires 480V, and I only have real 208V in the facility. I have a transformered up 480 subsystem, but its corner grounded rather than center grounded. The XPM3 manual suggests tha

Question on Grounding Resistor

Electronics Forum | Tue May 23 16:56:10 EDT 2000 | Ashok Dhawan

For grounding Table Mats/ Floor Mats and workstations, does grounding resistor need special characterstics e.g Wattage, material of construction, etc. We intend to use 1M Ohms resistor. EIA-625 does refer to EOS/ESD-S6.1 standard ( paragraph 7) fo

Voids in grounding pad of RF PCB

Electronics Forum | Tue Jul 30 21:44:13 EDT 2002 | sohct

Hi Anyone has experience in manufacturing RF PCB and encounter voids on the grounding pads? The grounding pad is covered by the a big component. Question is does voids in the solder joint affect the RF operation?

Re: Moisture related to ESD

from what I know the moisture does play a foctor in the ESD but if you are looking for wether or not it will provide more ESD I dont think so. If you keep your operators grounded with 2 Foot straps thats all the grounding that you need unless you are

ESD question

Electronics Forum | Thu Jul 28 14:13:52 EDT 2005 | rsmith@z-mar.com

It is important that the ESDS device, the operator, and the work surface maintain the same elctrical potential. ESD events take place when objects of different electrical potentil come in contact with each other. When these different charges equalize

ESD considerations during Conformal Coating?

Electronics Forum | Mon Jun 01 11:38:28 EDT 2009 | operator

So would the proper technique be as follows: 1. Grounded operator picks up PCB from ESD rack and attaches a 1meg(wrist strap cord)shunt to ground to a grounding surface on the pcb. 2. operator sprays conformal coating onto pcb using a spr

3-Phase Corner-Grounded Delta & GSM

Electronics Forum | Mon Aug 03 20:35:29 EDT 2020 | ttheis

We are looking at moving into a building that has drops from a three-phase 240V delta, corner grounded transformer. They currently have a lot of 230V Bridgeport milling machines and other motor operated equipment on this transformer. We are coming fr

Dave: The problem is always the cost.....also it is required to properly connect the work bench and top to the grounding system. With most installations what we find is after a year or so, people have moved the benches around and the grounding syst
