Description

This British Standard gives definitions, requirements, methods of test and recommended values of rated quantities for line traps intended to be inserted into high-voltage transmission lines to prevent undue loss of superimposed carrier signal.

It does not apply to inductors which may be connected to high-voltage transmission systems for other purposes, such as series reactors.

NOTE The titles of the British Standards referred to in this standard are listed on the inside back cover.

Definitions, general requirements for main coil, tuning device and protective device; blocking requirements, temperature rise, ability to withstand short circuit, insulation level, tensile strength of suspension system. Rating plates, type and routine tests. Recommended values of rated quantities.
