SXJS Portable Automatic Tan Delta and Capacitance | RFQ Sourcing Details

The SXJS is a portable, fully automatic dielectric loss tester designed to measure tan delta (tgδ) and capacitance (Cx) during field testing and maintenance of high-voltage electrical equipment.

Listed test objects include transformers, insulating bushings, capacitors, CTs, PTs, metal-oxide arresters, cables, CVTs, insulating oil, and insulation materials when the appropriate accessories and test configuration are used.

Operation combines automatic sample-type identification with in pacitance, internal or external high-voltage sources, and series or parallel dielectric-loss modes. Selectable single-frequency and automatic double-frequency conversion modes are provided.

The anti-interference specification states that the published measurement accuracy remains achievable under interference of up to 200%. The internal high-voltage setting range is 0.5–10 kV or 12 kV, with a maximum output current of 200 mA.

For external high-voltage testing, the unit accepts 40–70 Hz sources and supports UST positive-connection and GST negative-connection measurements. Its CVT self-excitation function measures C1/C2 capacitance and dielectric loss in one test. The listed low-voltage self-excitation output is 3–50 V and 3–30 A.

Field-oriented features include a backlit LCD with an English menu, a built-in thermal printer, storage for 255 data groups, and an RS232 interface for PC control, data processing, report export, and software updates.

The protection design includes high-voltage cutoff for short circuit or breakdown, low-voltage overvoltage protection, grounding protection, overcurrent protection, separated high- and low-voltage terminals, voltage and current monitoring, and an audible and visual alarm.

Supported operating conditions are -10°C to 50°C and less than 90% relative humidity. Input power is 180–270 VAC at 50 or 60 Hz ±1%, supplied locally or by a generator. Automatic 50/60 Hz identification and operation with frequency-fluctuating generator supplies are listed.

Procurement note: buyers should confirm the exact ordered voltage configuration, included leads and accessories, calibration documentation, applicable compliance documents, and suitability for their required test objects.

Source information gives conflicting warranty periods and differing delivery estimates, so the binding warranty, service scope, production schedule, packing details, and acceptance procedure should be established in the purchase contract before ordering.
