Professional Fuzrr ES1010 Wireless High/Low Voltage Current Ratio Tester (Malaysia)

For high-voltage power substation maintenance, transformer turn ratio testing, primary and secondary loop current measurement, polarity and phase verification, and live-line ratio diagnostics, advanced wireless testing equipment is critical. MTM Precision Sdn. Bhd. is proud to present the official Fuzrr ES1010 Wireless High/Low Voltage Current Ratio Tester in Malaysia.

The Fuzrr ES1010 (also known as a high and low voltage CT wireless ratio tester) is a comprehensive testing system composed of a high-voltage detector, a low-voltage current clamp, a main receiver host, a 5-section telescopic high-voltage insulation rod, monitoring software, and communication cables. Utilizing fast digital circuit processing technology, the ES1010 allows technicians to measure transformer transformation ratios up to 60kV without disconnecting lines or interrupting power. It measures high-voltage primary currents, low-voltage secondary currents, phase angles, and polarity while calculating transformation ratios, ratio errors, and phase differences in real time.

Below is an extensive technical breakdown of the product applications, key features, and detailed specifications for the ES1010 model, presented cleanly in plain text without tables or inline citation markers.

Product Applications

High-voltage transformer primary and secondary loop current ratio testing in electrical sub-stations
On-line measurement of transformer transformation ratios, polarity, and phase without power interruption
High-voltage primary line current testing (up to 60kV insulated sheath or 35kV bare wire)
Low-voltage secondary circuit current testing and load current evaluation (0.0mA to 20A range)
Substation commissioning, transformer health audits, ratio error verification, and power grid maintenance

Key Features & Operational Advantages

Simultaneous High & Low Voltage Measurement: Measures both high-voltage primary circuits (up to 1200A) and low-voltage secondary loops (up to 20A) simultaneously.
Live-Line Transformation Ratio Calculation: Calculates actual current transformation ratios, conversion ratios of secondary circuits (e.g., 5A), 10kV-YY transformer conversion ratios (10kV/380V), and extreme ratios up to 1:10 million.
Wireless Data Transmission (30 Meters): Transmits test data wirelessly over a straight-line distance of up to 30 meters between the detectors and the handheld receiver host.
5-Section Telescopic Insulation Rod: Supplied with a 5-section extension insulation rod totaling 5 meters in length, tested up to AC 60kV/rms insulation strength.
