The types of operating principle of voltmeter are the rectifier type(A.C), and moving
iron type(A.C) the voltmeter is used with a potential transformer externally mounted
in case of high voltage. |

ㆍFor higher ranges than 300V, use potential transformer(P.T) with a 150V A.C voltmeter
But the voltmeter of 600V is able to supply by order of customer.
ㆍWhen lettering the voltage ratio on voltmeter, the meters for 3phase 4wire are lettered as like
as the meters for 3phase 3wire. namely on 3phase 4wire in case of the indicating for
line-to-line voltage by line-to-ground voltage, and line-to-line voltage by line-to-line voltage,
he meters are not wited the √3
ㆍFull scale of voltmeter when use the P.T the standard calibration value of voltmeters are
150V and/or 300V but, the full scale of voltmeters are indicated the 30Kv, 9000V, 4500V and
600V etc. |
