Description
From the medium-voltage instruments the series inherited self-test of the electronics, battery and electrode, dual light and sound signalling and operation in rain and snow. The detectors are made for one voltage, for a range or in a switchable dual version, and besides the standard 50 Hz, 60 and 16.7 Hz are possible. The capacitive method passes a current of a few microamperes from the indicator through the air to earth, the resistive method through a resistor chain and a second pole, and the non-contact one works as a field probe. The KP-Test 5HL with a hook electrode of 70 mm diameter is made for 30–220 kV overhead lines. The KP-Test 5H+ has an immersion depth of 898 mm and a total length with stick of 2478 to 5806 mm, the KP-Test 5HVDC is supplied only with sticks of 4706 or 7250 mm, and all three are designed to IEC 61243-1. The non-contact 5D dual is fixed on an earthed grading ring, and its proportional audible signal warns in advance of approaching a live conductor. The two-section 5D-S dual has a contact bar that finds the right point on the insulator without a parallax error. The non-contact models are tested to DIN VDE V 0682-417, and the 5D-S also to the GS-ET-32 principle.
How to choose
Start with the current type and voltage class. For overhead lines up to 220 kV the KP-Test 5HL is enough, overhead lines and outdoor switchyards up to 420 kV are checked with the 5H+, and DC lines are served only by the 5HVDC. The non-contact 5D dual switches between the 110 and 220–420 kV ranges, and the 5D-S dual for 110–420 kV for outdoor switchyards works with or without a handle extension. The series overview classes 420–765 kV as extra-high voltage, and for 1–36 kV there is the KP-Test 5 and 5L range.

FAQ
Which voltage detector is needed for a ±320 kV HVDC line?
The KP-Test 5HVDC is intended for DC systems from ±140 to ±320 kV, and it is supplied only with sticks of 4706 or 7250 mm length.
How does the non-contact KP-Test 5D dual voltage detector work?
It signals operating voltage when the field strength exceeds the set value. The instrument is fixed on the earthed grading ring of 110–420 kV overhead lines.
Can KP-Test 5HL be ordered without a stick?
Yes, the KP-Test 5HL for 30–220 kV overhead lines is also supplied as a separate unit, as is the 5H+.
How should HV voltage detectors be stored?
They are stored and transported in bags, wall holders are provided for rooms, and the periodic test and repair are carried out by the factory service.
