Tan
Delta (also referred to as "Power
Factor") is the ratio of the
Resistive Power versus the Capacitor
Power of the dielectric material. It
is the measure of the quality of the
insulation medium. The TD60 provides
the testing and commissioning engineer
with a high voltage tan delta
measuring system suitable for testing
cables: XLPE, PE, EPR, PILC and other
electrical equipment: capacitors,
switchgear, transformers and rotating
machines.

H.V.
Diagnostic SARL produce 2 models TD30
for the TD Measurements up to max
voltage of 23kVrms (33 kV peak), and
the TD60 for TD Measurements up to a
max voltage of 44kVrms (or 62kV peak).
The TD30/60 is a battery powered
system that is diectly connected to
the HVA30 Series of VLF Test systems.
The TD30/TD60 uses standard C Type
akaline batteries which last for 10
hours thus providing the capacity for
many tests.
The TD30/TD60 is supplied
with 10 meters of output cable which
is terminated to suit the HVA30/60
test system. The TD30/TD60 is supplied
complete with operating software which
gives a complete picture of the tan
delta measurement together with a real
time wave form of the output voltage
and current. The Data transmission to
a Laptop PC or PDA is via Bluetooth
wireless communcation thus eliminating
hardwires or fibre optic cables to
minimise the hookup time and operator
errors.
