<p>PURPOSE:To enable to perform easily an inspection, etc., of the titled transformer by a method wherein on the way of change-over connection from an amplifier for normal use to a spare amplifier, both amplfiers are connected in parallel temporarily between a signal detector and the load circuit of a receiving part. CONSTITUTION:When a change-over switch 5A is in the change-over position 6 in operating time, an output signal of the signal detector 1 is inputted to the amplifier 2 through contacts 5a-5b, and an output signal thereof is transmitted to the load circuit 4 through contacts 5e-5f. The spare amplifier 3 is released at this time. When the change-over switch 5 is transferred to the change-over position 7-8 next, both the amplifiers 2, 3 are operated in parallel at the middle change-over position 7, the amplifier 2 is released at the change-over position 8 next, the spare amplifier 3 only continues operation, and the output signal of the signal detector 1 is transmitted to the load circuit 4 through the spare amplifier 3 without being interrupted.</p> |
