ORDERING PROCEDURE
When ordering, one must specify: the name and type of the voltmeter,
the voltage measuring range, the working position according the
table 1, the kind of the version and the acceptance test mode.
Ordering example: code EP29-5-D-00-7 that means: an EP29
voltmeter to co-operate with a X/100 V measuring voltage transfor-
mer, working position: =45° from the horizontal position, standard
version and delivered with a quality inspection certificate.
1)
The number code is established by the producer.
2)
Additional requirements must be agreed with the producer.
* 150 V - Widened input signal range, adapted to measuring
transformers, e.g. 10,000/100 V when the 15 kV range
printed on the scale
** 133.3 V - Widened input signal range, adapted to measuring
transformers, e.g. 600/100 V when the 8 kV range
printed on the scale.
