Short one: Whats the L symbol in ANSI
(OP)
Hi
Short one:
What is the L in circle(same as A in circle is ammeter, V in circle is Voltmeter)?
The L thing is conected in paralel with the voltmeter.
Thanks

RE: Short one: Whats the L symbol in ANSI
My guess, since it is in parallel with the voltmeter, would be L = LOAD

This is something generic, but i expect to have there a device, something touchable. It is connected like a voltage (undervoltage or overvoltage) relay.
System is IT.
Could be some remote CT for insulation monitoring, which provides signal to a central differential (51N?) protection mounted in main switchboard?
Other posibility: making all documents in english is a fashion and need, in all emerging markets, due to different nationalities parts involved in projects(ex: a chinesse investor, czech engineering company, german constructor, investment based in Hungary....). So maybe the engineer does'n speak so well english, or in his language, L means something obvious. I hope i am wrong and this remains a (bad) joke.

What is a lowering relay ?
RE: Short one: Whats the L symbol in ANSI
A lowering relay, whatever that is, would not be in parallel with a voltmeter.
To know for sure, you'll have to ask the developer of the one-line or get the information from a list of materials.
