T 26 / 1
The T 26/1A and T 26/1B high-voltage test sets are efficient, mobile systems for high-voltage testing of cables, cable systems and installations as required by current regulations (VDE) with DC voltages of up to 400 kV and 650 kV respectively. The sets are suitable for both installation in measuring trailers and onsite testing as stationary test set. The spatial separation of the operating and high-voltage units makes it possible to operate the sets from outside the immediate danger area. Their modular structure makes them easy to set up on site and allows adaptation to measuring tasks.
The sets are primarily designed for power supply companies, cable laying firms and cable manufacturers for the DC voltage testing of high-voltage systems and cables. Their short-circuit-proof output circuit and high power make them suitable for use in fault location as a burn-down unit for burning high-impedance and intermittent cable fault.
Salient features:
- Individual assembly of each set from function blocks
- Combinable cascades in voltage steps of 200 and 250 kV
- Travelling wave protection by means of liquid resistor (acts simultaneously as a discharge resistor, resistors embedded in cast resin are used up to 150 kV)
- Discharge switch
- Cascades with SF6 gas isolation (isolated with cast resin up to 150 kV)
- Thermal overload shutdown
- Switch clock
- Automatic current range switching
- Preselection of excess current shutdown and selection of voltage measuring range by button
- Cane be used as burn-down unit in fault location
- Great mobility
- Simple, safe operation
