Page 9 All manuals and user guides at all-guides.com GENERAL INTRODUCTION The test and diagnosis system TDS40/60 shall be used for the stated field of application in cable diagnosis and cable testing only. Any other application is strictly forbidden! Megger cannot be made liable for any damage to persons or matter caused by using the system for some other application.
Page 10 Failure to observe them can render the measurement results useless. Working with products from Megger It is important to observe the generally applicable electrical regulations of the country in which the device will be installed and operated, as well as the current national accident prevention regulations and internal company directives (work, operating and safety regulations).
Page 11 In this case inform the person in charge who should inform the Megger-service to resolve the problem. The instrument may only be operated when the malfunction is resolved.
Page 12 A CO2 fire extinguisher must be always available within electrical installations. • If, contrary to the regulations, any other extinguishing agent is used for fire fighting, this may lead to damage at the electrical installation. Megger disclaims liability consequential damage.
Page 13 Due to the integrated breakdown detection, this test process takes place without damage to the fault-free cable insulation. In combination with the partial discharge measurement system PDS 60, the TDS40/60 forms a fully adequate diagnosis system (TDS NT) which is suitable for the partial discharge diagnosis on medium voltage cables according to the standards.

Page 16 All manuals and user guides at all-guides.com Description of the Test Procedure with VLF-Voltage Because of the space charges formed in the dielectric of the cable, DC test methods prove to be dangerous when applied to PE and VPE cables and should therefore never be used on such types of cables.
Page 17 All manuals and user guides at all-guides.com Another vital characteristic to be considered when designing this system was to ensure simple on-site testing by small dimensions, light weight and low power consumption. Every cycle starts with a charging phase in which the test object as well as the back-up capacitor switched in parallel are charged from a DC source until the desired test voltage is reached.
Page 18 All manuals and user guides at all-guides.com The loss of voltage caused by twice changing the polarity (device option Basis) will now be compensated for by recharging with the negative DC source. In contrast to this at the device option Plus the losses of a polarity reversal are immediately compensated. The back-up capacitor has the following tasks: - It slows the ring-around event down to the ms range even for short cables, - It compensates a part of the losses during the polarity reversal.
