Application
Every electrical equipment, apparatus or machines are provided with insulation between the live part and earth or between two or more different sections of live parts. This insulation is required to be tested at high voltage values as required by applicable standards. For electrical equipment, voltage withstand test at different levels is specified, which depends upon the working voltage of the equipment. H.V. Testers are compact, rugged and portable test sets used for DC dielectric breakdown testing. Typical applications include testing of transformers, switchgear, cables, capacitors, aerial motors platforms, hot sticks bucket bricks, vacuum bottles and other related equipment like vacuum interrupters, blankets, ropes, gloves, hydraulics hose, instruments transformers generators.
Description
H.V. testers are specifically designed for safe and accurate measurement of leakage current to evaluate insulation integrity. These testers are portable, one end ground test systems, ideal for H.V. testing. Accurate leakage measurements are ensured by placing the current meter in the return of the H.V. path. Many features which Tesca provides as standard are either offered by competitors as optional features or not at all. Years of Design, engineering and manufacturing experience have made H.V. testers the most durable, easily operated and the best designed sets in the industry.
