Overview

T&R Test Equipment is a market leader in the field of protection test equipment. The range includes primary and secondary test equipment up to 6000 Amps, voltage sources, micro-ohmmeters and high voltage test systems up to 100kV. The PT18-10 and PT30-10 high voltage DC test sets are designed to perform tests on insulated cable and jointing systems. The units have a variable output voltage with a maximum of ±18kV DC (PT18-10) or ±30kV DC (PT30-10). Both units have a maximum charging capability of 10mA. A zero-volt interlock is fitted that prevents the output being switched on unless the output control is at zero

Features

  • Model PT18-10: ±18kV DC Output Voltage
  • Model PT30-10: ±30kV DC Output Voltage.
  • 10mA output capability.
  • Both voltages and current metered on HV outputs.
  • Automatic earth system for dumping capacitive loads.
  • High Voltage output plug and socket system.
  • Key operated supply switch to prevent unauthorised operation.
  • Zero-volt interlock.
  • Visual indication of test piece failure.
  • Automatic mains voltage selection.
The unit includes an automatic load discharge system that discharges the cable under test when the output is switched off or breakdown occurs. The internal dumping system can discharge a maximum of 2.5kJ on each output, corresponding to 10µF at 18kV or 4µF at 30kV. In the event of a test object failure, the overload circuit will automatically switch OFF the output voltage and earth the output via the internal discharge circuit. A manual discharge probe is also supplied as standard with both units, allowing higher load capacitances to be safely discharged.
The mk2 units introduce automatic 115/230V AC mains voltage selection, allowing easy transition between site voltages.
The output voltage is metered by a large linear, analog instrument scaled 0 to 20kV (PT18-10) or 0 to 30kV (PT30-10). Test object current is metered by two further analog meters with 0 to 10 scale marking. The meters read 0 to 10mA directly, or 0.1mA when the divide by 10 push button is operated. The HV output from both units use a high quality plug and socket system, allowing for easy cable replacement.
The PT18-10 and PT30-10 are part of a comprehensive range of AC and DC High Voltage systems manufactured by T&R Test Equipment. The line-up includes cable test sets from ±15kV to ±30kV DC and pressure test systems up to 100kV AC.
