@3DDave yes there is one input source only, @ Parchie @ JWR01 AC Filter capacitors 3no's 200µF-250VAC opened and checked its value is ok, Actually which capacitor failed? you people Mentioned about capacitors There is DC capacitor also 2000µF and some other filters too, please check the attached...
@Kiribanda,
UPS both source are same, UPS is just power ON and it goes to Bypass mode with the above message, may be something in Electronics, but how to contact manufacturer because it's old already.
@Kiribanda,
Bypass and main input source is the same supply. also we disconnected the load already, this UPS is in idle condition without load, just input supply and it gone to bypass mode with the same message A13 "INV OUT TOL", is anyone face the same issue before?
@Parchie
Yes this Manual we have already, I just want to know how to fix it? Before anybody face the same trouble?what should we should action to solve this trouble.
Dear,
40 KVA Astrid UPS giving Alarm A13 "INV OUT TOL" ( inverter output voltage out of tolerance), Also UPS going to Bypass mode. What can be the possible causes? How we can fix this problem? Thanks in advance
Dear All,
We Have 33 KV filter bank circuit for Compensation plant which include Line CT, Reactor and capacitors bank, we are facing trouble as this one phase circuit is tripping with Thermal protection and others are Ok, reactor value 11.85mH, Line CT 1000/1, Unbalance CT 10/5 CPR-04 relay is...
Dear Anoter, the Attached file is your last year complete file which you solved with another circuit and parameters and it was correct. same file I am using for this circuit and just eliminated the Resistance circuit and Put other parameters. hopefully it will work fine. please check the last...
Last year you solved this problem with another circuit and it is correct calculation, it was matching with Matlab result, I am attaching the Last year same file.https://files.engineering.com/getfile.aspx?folder=39cb3c5c-f132-49de-ba90-bd5a328d6c55&file=L_and_C_filter.xlsx
@ Anoter, I prepared excel workbook simply and Eliminate the Resistance, because I am looking Finally for I0 only between 2 star, and as per my excel worksheet you can understand i simplified the circuit and the result also coming nearby correct, last year you also send the file with this...
@Anoter sketch is like that, I mentioned the 12 capacitance values Red and Blue colour, Resistance in the circuit, if we calculated in series Star1 R phase R=126.15µf & 44.7343434774307 µf then it will 33.0237242 µf, so for all it will become 6 Values only and we can put in Formula which we...
thread238-468572,
Dear Anoter,
due to Affected by Covid-19 last year i stopped posting the reply of the Thread 238-468572,
can we remove the resistance from the attached circuit and Calculate the neutral current same as you did in previous circuit, in place of 12 microfarad values. can we make...
Dear@ Anoter,
I understand its same file and is for user understanding, but my Question is that RLC circuit why IoA & IoB?
in LC circuit it was Io only,if IoA and IoB also here it should be Equal if i am not wrong same like LC circuit. Finally I am looking for Io ( unbalance current ) in between...
Dear@Anoter and all the Engineers here, i was bit busy as same Filter Bank trouble in Plant, lot of capacitors blown, this LC Circuit it was unbalance 30% trouble time, but with the help of you ( Anoter) formula we Rearrange the capacitors and bring down to 1%, thanx once again to the entire...
