Longitudinal Balance Measurement of Central Office Equipment

Longitudinal balance should be measured by a standard method that will accurately show the degree of unbalance to ground of components or networks. The method proposed by the IEEE´s Wire Communication Committee and under consideration by International Telephone and Telegraph Consultative Committee (CCITT), was tested, using techniques found necessary to avoid errors. Calculated data were used to prove the precision of measurements, and are included to indicate the magnitude of unbalance caused by resistors, capacitors, and inductors.
