Operation and Function
Warning! For operation the following instructions have to be really observed.
2.1 Types of Contact Electrodes
The
PHV I Phase Comparator
is equipped with an integrated test electrode. The test
electrode is designed as a tooth profile for a safe approach. In addition, the M8 thread
integrated in the tooth profile of the test electrode allows a flexible use of different
threaded contact electrodes.
Note:
The contact electrodes are not included in delivery.
The contact electrode required for the respective installation is firmly screwed into the
top end of the test prod. The nominal voltage (nominal voltage range) of the respective
contact electrode has to correspond to the nominal voltage (nominal voltage range)
of the phase comparator (see Table 1).
