Partial Discharge measurement according to IEC 60270 can be performed in single- and three-phase applications with the model PD2U and PD3U respectively. Phenix Technologies can provide an entire PD measuring system including the coupling quadrupole, preamplifier, measuring device, calibrator and coupling capacitor C = 250…1000 pF, U = 100…400 kV. For measurements in noisy environments, it is possible to exclude the disturbance signals from the measurement with an antenna used in conjunction with the noise gating function incorporated in the measuring device.

C tan δ

The dielectric losses in electrical insulation are measured with a tan δ-bridge. A tan δ-bridge is a highly sensitive measuring instrument, capable of measuring losses in insulation down to 10-5 times the apparent power demand during AC voltage excitation. Such small losses can only be measured by comparison against an SF6 gas insulated standard capacitor through a bridge circuit. To measure the losses of large capacitive loads requiring high excitation currents, Phenix Technologies also provides a current divider. The standard field use equipment is rated for 100 kVrms. At Phenix Technologies’ headquarters in Accident, MD, USA, C tan δ measurements can be made up to 750 kVrms. C tan δ


This high voltage test set can be used to apply an AC high voltage for testing capacitive loads. Therefore, it is excellent for testing insulators, capacitors, overhead lines, high voltage switches, cables, motors, and generators. This test set consists of a control panel, variable voltage source and high voltage reactor with three different high voltage taps (25, 40 and 50 kV). This unit is rated for 500 kVAr at 50 Hz, and 415 kVAR at 60 Hz, with a duty cycle of 5 minutes ON and 15 minutes OFF. E.g., it is possible to test a cable at 50 kV and 60 Hz up to 6 miles (10 km) length.


This mobile test set is a variable high voltage inductor. That means constant frequency, but the inductance can be adjusted to resonance. Each module can provide 320 kV and 4.2 A at 60 Hz; for a total output power rating of 2.7 MVA. In parallel module connection, it is possible to test a capacitive load C = 3.5…70 nF, up to 320 kV. In series module connection, it is possible to test a capacitive load C = 0.9…17.5 nF, up to 640 kV. The unit is rated for a duty cycle of 1 hour ON and 1 hour OFF.


This capacitive high voltage load bank is specified for up to 300 kV and 28 MVAr capacitive power at 30 Hz. The main purpose is to simulate a load of a high voltage cable when testing high voltage reactors. It is also possible to simulate a high energy cable discharge test, as may be associated with DC or VLF AC testing of long high voltage cables.

In addition to this large capacitive load bank, Phenix Technologies is able to provide other high voltage capacitive loads for higher voltage ranges and lower capacitive values. E.g., C = 0.5…10 nF up to 1.2 MV.


Phenix Technologies can provide a PD-free high voltage up to 750 kVAC at 50 or 60 Hz. Phenix’s indoor high voltage test hall with a ceiling height of 70 ft (21 m) can easily handle large high voltage components up to 40 US tons (36 metric tons) in mass. The uncertainty for voltage measurements is less than 0.3%.
