High voltage detector calibration
Voltage detectors are crucial for checking for voltage on medium and high switchgear, transformers, or overhead lines.
• voltage detectors are designed to issue a clear, double signal if any voltage is applied.
• The KP-Test 5 Series voltage detectors from Pfisterer provide user comfort and safety in one electrical safety device.
• The KP-Test 5 series from Pfisterer perform an automatic self-test when switched on, providing a ready signal if the test is successful and the device is functioning properly.
• The KP-Test 5 series can be supplied as capacitive single-pole voltage detectors for a.c. voltages from 1V to 420kV, or resistive double pole voltage detectors from 500V to 4,000V.
• The KP-Test 5 series includes KP-Test 5 for medium voltage (MV) switchgear and electrical equipment applications with contact electrode extension, KP-Test 5 dual for medium voltage (MV) applications with contact electrode extension and nominal voltage range selector, KP-Test 5L for medium voltage (MV) overhead line systems, KP-Test 5H for high voltage (HV) applications with contact electrode extension, KP-Test 5HL for high voltage (HV) overhead lines, KP-Test 5R for Catenaries, KP-Test 5R for Catenaries Separable, KP-Test 5R DC for catenary systems of DC voltage railways, KP-Test 5R DC dual, and KP-Test 5 DC for catenary systems of DC voltage systems and railways with a third rail.
use of voltage detectors
Before using voltage detectors, checks should be carried out for visual damage, note the date of the next routine inspection, and check the maximum permissible voltage range use.
• For cleaning and maintaining medium and high voltage detectors, a damp, fluff-free cloth should be used.
• MV HV electrical safety considerations include disconnecting the electrical system, ensuring against reconnection, establishing absence of voltage, short circuiting & portable earthing, and insulation, isolation, and protection against adjacent live parts.
