Every electrical apparatus specifies a particular power frequency voltage withstand test depending upon its own working voltage level. Our H.V. Tester offers the break down voltage right from 2kV to 600kV . The standard voltage levels available with us are 2kV, 5kV, 10kV, 15kV , 20kV, 25kV, 30kV, 50kV, 100kV, 150kV, 300kV and 600kV. The test set up to 30kV are manufactured in air cooled design, while the sets above 50kV are manufactured in oil cooled design. The output of AC. H.V. Tester is single phase. 50Hz,
While the out-put in DC. H.V. Tester is in the pair of +ve & -ve probes usually the –ve Probe is grounded with the body of H.V. tester
Features:
1) Manual OR Motorised version
2) Heavy duty H. V. Transformer.
3) Precisely calibrated Electronic circuit breaker.
4) Universally accepted & Tested design.
5) Customised design & construction also available. |
