TANDO 700
High-precision measuring and analysis system for
dissipation/power factor and capacitance
High-voltage insulation testing made safe, easy and reliable
Why dissipation/power factor and capacitance?
Early loss detection improves performance
The condition of insulation is essential for secure and
reliable operation of high-voltage (HV) electrical equipment. Measuring dissipation/power factor (Tan Delta)
and capacitance helps you to determine overall insulation
condition of:
Variations in the dissipation/power factor are often signs of
mechanical displacements, the ingress of moisture, partial
discharge, aging and degradation in insulation.
By detecting these conditions early, corrective action can
be taken to improve the performance and reliability of
electrical equipment.
> Rotating machines (motors and generators)
> High-voltage cables and cable accessories
Our TANDO 700 system provides you with a precise and
extremely safe measuring solution that makes insulation
tests easier and more reliable. It can be used for insulation
material tests in research labs as well as production quality
checks in factory HV test fields.

Highly precise, reliable data
The robust TANDO 700 provides you with extremely high
measurement accuracy (typical < 5 x 10 -6). It is suitable for
use in environments with interference, such as in power
plants, substations and unscreened test labs. The system
continuously verifies signal quality through Fast Fourier
Transformation (FFT) analysis.
TANDO 700 is a complete digital test and analysis system
used to measure dissipation/power factor and capacitance
in the insulation of high-voltage equipment.
Flexible testing solution
TANDO 700 measures both ungrounded and grounded
test objects, since it can be operated on HV potential. The
system is compatible with any type of reference capacitor
for testing a variety of HV equipment
Long, continuous measurement
TANDO 700 measurement channels are equipped with
a powerful internal battery. The system’s low power
consumption allows for long measuring periods without
having to recharge the internal battery. For even longer
measurement sessions, an optional external battery can be
added as an auxiliary power supply.
TANDO 700 can directly measure currents in a dynamic
range from 5 µA to 1 A. The input range can be extended
up to 28 A by means of optional external shunts.
Compact, portable design
Safe, plug-and-play operation
TANDO 700 includes two measuring units and a fiber optic
converter, which is linked with a USB connection to any
desktop PC, rack-mounted computer or laptop. This simple
system design enables easy transport to various lab and
field areas.
The easy-to-use TANDO 700 software automatically
recognizes connected hardware for easy plug-and-play
operation. Fiber optic connections ensure complete
galvanic isolation for superior safety in HV areas.
Additional measurements
TANDO 700 also measures power, voltage, current, impedance and frequency. All measurement data is displayed
and analyzed in real time. The modular system can also be
used with our MPD 600 for simultaneous measurement
and analysis of partial discharges.
