Transformer voltage ratio meter on-site calibration: The lines are connected according to the wiring diagram, with the load box串联 between the secondary terminals a and x of the voltage transformer under test. The grounding point of the load box must be reliably grounded. Adjust the load box to the actual secondary load of the current transformer under test. Select the power factor positions of 0.8 and 1.0. Short-circuit and ground the secondary circuit of the voltage transformer. Ensure that the secondary winding of the voltage transformer has only one grounding point during operation. The experimental wiring should be correct, and the measured secondary winding and other secondary windings must not be short-circuited. The inspection work must be thorough and meticulous, with double-checking, familiar with the performance of the experimental instrument and inspection methods. Therefore, we must strictly follow the work sheet and maintain all sections of the load box.
