PD-TaD 80 For your safety
822-188-3 11 / 74
No operation with condensation
Condensation can form in devices and systems due to temperature fluctuations and high air
humidity, which in some components can lead from leakage currents and flashovers up to
short-circuit.
Maximum danger arises when relatively high air humidity and temperature fluctuations occur
in a device consecutively, e.g. which is the case when storing the device in an unheated
room or when placed outdoors. When the device is then exposed to a high ambient
temperature, the cold device surfaces cool the air in the immediate vicinity, which leads to
formation of condensation even inside the device.
In this process, two factors are crucial:
The higher the relative air humidity, the faster the dew point is reached and water is
condensed.
The higher the temperature difference between the surfaces and the ambient air, the
stronger the tendency for condensation.
Always prevent condensation in devices. Temper the device and system before and
during the measurements so that no condensation occurs.
No operation in areas with risk of explosion and fire
Measurements in direct contact with water, in environments with explosive gases and in
areas with fire risks are not permitted. Possible danger zones are e.g. chemical factories,
refineries, lacquer factories, paint shops, cleaning plants, mills and storage for milled
products, tank and loading plants for combustible gases, liquids and solid matter.
Lifting and carrying the transport cases
To transport the transport cases containing the PD-TaD 80 and accessories, pull them
along on their wheels.
The transport cases and their contents weigh approx. 42.0 kg or 22.5 kg.
Lifting or carrying the transport cases requires two people.
2.3.1 Dangers when working with high voltage
During tests and measurements with the PD-TaD 80, dangerous - at times very high -
voltage is generated that is fed to the test object via an HV connection cable.
Personnel need to pay special attention and must be very careful while working with high
electric voltage.
Commissioning and operation of the PD-TaD 80 are permitted only in compliance with the
EN 50110 and EN 50191 (EU/EFTA countries) or with standards applicable in your country.
Observe 5 safety rules
Comply with the following safety rules before beginning tasks in and on the electrical
plant:
1. Disconnect the test object.
2. Secure against re-connection.
3. Verify absence of operating voltage.
4. Earth and short all phases.
5. Provide protection against adjacent live parts.
