Transformer main performance measurement index 1. Basic electrical parameter test items (1) Three-phase AC voltage Ua, Ub, Uc and voltage mean U
(2) Three-phase alternating current Ia, Ib, Ic and current mean I
(3) Grid frequency F
(4) Active power Pa, Pb, Pc and three-phase total active power P
(5) Reactive power Qa, Qb, Qc and three-phase total reactive power Q
(6) apparent power Sa, Sb, Sc and three-phase total apparent power S
(7) Power factor PFa, PFb, PFc and power factor mean PF
2. Measurement of the corresponding parameters of transformer no-load and load There are nearly 100 types of transformer nameplate parameters stored in the database of the instrument. When measuring the transformer, corresponding parameters of the model in the database can be provided for the corresponding model of the transformer. If the unknown model transformer, that is, the nameplate parameters are incomplete or vague so as to provide incomplete parameter, the instrument's electrical parameter measurement interface provides a dedicated no-load measurement and load measurement interface for the user to measure the parameters of the transformer. The measurement method can be selected as three-phase three-wire measurement or three-phase four-wire measurement.

FS-0906 Transformer Economic Operation Measuring Instrument Main Performance
FS-0906 Transformer Economic Operation Measuring Instrument is an instrument developed and produced by the company on the basis of the transformer loss parameter intelligent tester for real-time measurement and determination of the transformer operating status. It is a special test instrument developed according to the GBT--13462-2008 TUW national standard. . The instrument realizes human-computer interaction through an 8-inch touch display screen, displaying measurement data in sub-categories and pages, and an external data printer. The measurement data is recorded in real time or periodically. The on-site measurement can be directly used with the measurement power supply without additional 220V power supply.
