Hi,
Anyone here have applied a HRG (high resistance grounding) scheme on a 60kW EDG? Our process engineers are saying that the system that the EDG is supplying should be ON at all time as much as possible but I feel that putting one on that small load is not worth spending a NEMA 3R resistor...
Hi,
Got a question on bringing a multi-core control wiring from the PLC cabinet to MCC with type 2B or 2C control wiring. It says in the definition of NEMA that there is interconnection between control terminal blocks among different buckets in the MCC. Does that mean that neutral/common...
Got a question for you guys.
Whenever we want a PLC ON/OFF status for the motor, we would run cables, provide a NO contacts to the PLC in series with the motor starter coil (see attached VACULOADER SCHEM 2.pdf). Now our engineer wanted to use EATON'S electronic overload relay (C441) and wanted...
Hi,
I'm usually confuse on how to tell if a particular device gives an analog input to the PLC or does it need an analog input from the PLC (hence PLC output). I usually get my way around by talking to the vendor. By looking at it based on the drawings e.g. for the kinetrol actuator that I'm...
Hello,
I'm currently making a technical report on the PAGA location for our project. But I got bogged down because I disagree with my KP on the subject of computing the line for a loop of speakers.
Our PAGA speaker loops/system, has the following parameters: 100v supply, 300w amplifier(but...
Hi Everyone,
I'm working in a design engineering firm (EPC) as an electrical engineer for more or less 4 years now. But my work only involved detailed engineering (layouts, typical installations, estimation,etc.). I really like to be exposed in upstream engineering job but my employer does not...
