Transformer Capacity and Loss Tester| XHTX1318
The XHTX1318 transformer characteristic tester is a multifunctional measuring instrument that combines the capabilities of a transformer capacity tester and a transformer characteristic parameter tester. It provides precise measurement of power frequency parameters including transformer capacity, type, no-load current, no-load loss, short-circuit (load) loss and impedance voltage for various distribution and power transformers, helping users quickly verify transformer ratings and energy efficiency performance on site.
Applications & Target Audience: Designed for transformer manufacturers (capacity and loss acceptance testing), power supply utilities (electricity inspection and transformer rating verification), substation commissioning teams (no-load and load loss measurement), third-party electrical testing institutes, and industrial power departments in mining, metallurgy and rail transit that need fast on-site verification of transformer capacity, no-load loss and load loss parameters.

FAQ
Q1: What parameters can the XHTX1318 transformer characteristic tester measure?
It measures transformer capacity, type, no-load current, no-load loss, short-circuit (load) loss and impedance voltage, covering the key power frequency parameters needed for transformer rating verification and energy efficiency assessment.
Q2: What is the capacity test range of this tester?
For 10KV oil immersed and dry type transformers the range is 30KVA~2500KVA; for 35KV oil immersed transformers it reaches 50KVA~31500KVA; 20KV and 35KV dry type transformers are supported from 50KVA~2500KVA and 50KVA~2000KVA respectively.
Q3: What is the measurement accuracy?
Voltage accuracy is ±0.2%, current accuracy is ±0.2%, and power accuracy is ±0.5% (CosΦ>0.1) or ±1.0% (0.02<CosΦ<0.1), ensuring reliable test results for field acceptance and inspection work.
Q4: How are test results stored and printed?
Up to 500 test results can be stored with power-down protection, and the built-in thermal printer allows immediate result printing at the job site. 40 user-configurable sample presets speed up repeated testing.
Q5: Can the measurement range be extended?
Yes. The instrument is compatible with external voltage and current transformers, allowing extended range measurement beyond the built-in 0~100A current and 0~1000V line voltage ranges.
