Product Detail

Description

The induction withstand voltage test of transformers and transformers is an important test to ensure product quality meets national standards. The longitudinal insulation induction withstand voltage test between turns, layers, sections and phases of transformer windings is an important item in the transformer insulation test. The vertical insulation test needs to pass the frequency multiplier power supply device, apply the test voltage, and carry out the withstand voltage test.

Analysis of Grounding Transformer Operational Behavior Under System Single-Phase-to-Ground Fault Conditions

1 Theoretical AnalysisIn distribution networks, grounding transformers serve two key roles: powering low - voltage loads and connecting arc - suppression coils at neutrals for grounding protection. Grounding faults, the most common distribution network fault, heavily impact transformers’ operating characteristics, causing sharp changes in electromagnetic parameters and status.To study transformers’ dynamic behaviors under single - phase grounding faults, build this model: Assume a tr

Design Calculations for Neutral Grounding Schemes and Grounding Transformer Sizing in Utility-Scale Solar PV Plants

1 Classification of Neutral Grounding Methods for Solar Photovoltaic Power StationsInfluenced by differences in voltage levels and grid structures across regions, the neutral grounding methods of power systems are mainly categorized into non-effective grounding and effective grounding. Non-effective grounding includes neutral grounding via arc suppression coils and neutral ungrounded systems, while effective grounding comprises neutral solid grounding and neutral grounding via resistors. The sel

Zero-Sequence Impedance Characterization of Dry-Type Grounding Transformer with ZN Connection

In a neutral-insulated three-phase power system, an earthing transformer provides an artificial neutral point, which can be solidly earthed or earthed via reactors/arc suppression coils. The ZNyn11 connection is typical, where zero-sequence magnetomotive forces in the inner/outer half-windings of the same core column cancel out, balancing fault currents in series windings and minimizing zero-sequence leakage flux/impedance.Zero-sequence impedance is critical: it determines fault current magnitud

Case Analysis on Maloperation of Grounding Transformer Overcurrent Protection Relay

The neutral grounding mode refers to the connection between the power system neutral point and ground. In China's 35 kV and below systems, common methods include ungrounded neutral, arc-suppression coil grounding, and small-resistance grounding. The ungrounded mode is widely used as it allows short-term operation during single-phase grounding faults, while small-resistance grounding has become mainstream for its fast fault removal and overvoltage limitation. Many substations install grounding tr

Discussion on the Design of Low Zero-Sequence Impedance Grounding Transformers

With the expansion of power system scale and the cableization process of urban power grids, the capacitive current in 6kV/10kV/35kV power grids has significantly increased (generally exceeding 10A). As power grids at this voltage level mostly adopt neutral ungrounded operation mode, and the distribution voltage side of main transformers is usually in delta connection, lacking a natural grounding point, the arc during ground faults cannot be reliably extinguished, necessitating the introduction o
