Voltage Detectors
I
One of the most important operations when working on electrical switchgear is to check
that voltage is absent, and this requires voltage detectors that meet the highest quality
Voltage Detectors

and reliability requirements. PFISTERER voltage detectors meet these requirements

without exception.
The KP-Test 5 Series voltage detectors provide an exceptional combination of user
comfort and safety in one device. The optimum LED layout, integrated audible signals
and innovative self-test features form the basic elements on all equipment types. Thanks
to our long years of experience, we are able to develop and supply voltage detectors that
work reliably even in critical situations in the field.
KP-Test 5 Series voltage detectors can be supplied as capacitive single-pole voltage
detectors for a.c. voltages from 1 to 420 kV, or resistive double pole voltage detectors
from 500 to 4,000 V, in various types.

Equipment types:
The possible operating conditions should be taken into consideration when selecting
a suitable voltage detector. Voltage detectors with a contact electrode extension have
universal application, as they allow reliable indications even in difficult electrical field
conditions.
