Capacitance & Tan-Delta Test System (Model TD-1)
The instrument
after some minor calculation directly gives the capacitance and
dissipation factor (Tan-Delta) of the insulating material when used
with the required power source. This is a battery operated instrument
and very useful to monitor the insulation health of the insulating
material as per IS. This instrument is specially shielded with high
permeability metal sheets to avoid the effect of external interference.
Features
- Built-in protection:
Instrument is provided with built in high voltage protection device
which protects the instrument & the operator against failure of
test object or standard capacitor.
- Null Detector:
Built-in battery operated null detector is provided which is most
suitable for quick balancing of the instrument. It gives high
sensitivity and accuracy.
- ICU: Interference compensation (unit) is useful only in the case of heavy induction area so the to get the correct readings.
Technical specification:
- Capacitance Range: 1 PF to 1.1MFD in three or four ranges depend upon capacitor and can be extended further (using external current transformer).
