B.1 Tools and Measuring Instruments
In order to be able to manage disturbances while driving, the following tools and measu-
ring instruments should belong to the equipment kept on board:
• Multi-meter for voltage (AC), frequency and resistance
• Measuring instrument for inductance
• Measuring instrument for capacity
• Current absorbing clamps
• Thermometer (ideal is a infra-red thermometer)
• Pressure device (pincer) for coolant circuit
B.2 Overloading the Generator
Please ensure that the generator is not overloaded. This must be considered, especially with
regards to multi power generators. In this case the extra load including the electrical performance
can be considerably greater than the drive performance of the motor, which can eventually lead
to a damaged motor.
The full nominal performance of the generator is fore-mostly for short term use. It is, however,
required to start electric motors with high starting current or achieve special starting procedures at
peak loads. 70% nominal load is ideal for a long motor life. (Continual use means uninterrupted
use of the generator for many hours). This should be taken into consideration when connecting
devices. This ensures extended motor life.
It is no problem for the motor to be run occasionally for 2 - 3 hours at full load. The complete con-
ception of Panda Generator ensures that even during extreme conditions, an overheating of the
motor will not occur. Accumulation of soot will occur if run for long periods at full load.
Effects of Short Circuiting and Overloading on the Generator
The generator cannot be damaged by short-circuiting or overloading. Short-circuiting and over-
loading suppress the magnetic excitation of the generator, thus, no current is generated and the
voltage will collapse. This condition is immediately offset, once the short circuit has been elimina-
ted and/or the electrical overload removed.
