Product Overview
YTJL10-32 primary and secondary fusion voltage/current integrated sensor is an AC sensor that complies with the technical specifications of the primary and secondary fusion equipment of the State Grid and is designed and manufactured in accordance with the requirements of the GB20840.1-2010 standard.The sensor can simultaneously output zero-sequence voltage and phase current, zero-sequence current sampling signals, and can be matched with the ZW32 column-mounted high-voltage switch. It has the characteristics of low power consumption, high accuracy, and three-in-one measurement, metering, and protection.
Product Features
Voltage Section
● Uses ceramic capacitors, offering good long-term stability and extensive grid operation experience.
● Features high operating current and strong anti-interference capability.
● Low output impedance, adaptable to various cables, overcoming errors caused by cables, with cable exchange error less than 0.1%.
● Features small accuracy changes affected by ambient temperature. Within the full temperature range of -40℃~70℃, the maximum change in error is less than 0.25%, fully meeting the temperature variation index requirements of 0.5-level sensors as stipulated by the standard.
● Secondary signals are output through an isolation transformer, providing better safety and anti-interference capability.
Current Section
● Phase current and zero-sequence current are wound with independent coils, and the zero-sequence current is obtained using the current synthesis method.
● The error of the zero-sequence current output is less than 1% when the primary current is 1%~120% of the rated current (1A~24A), and less than 10% when the current is 10 times the overload.
● Manufactured using low-temperature drift iron core, the error variation meets standard requirements within the temperature range of -40~70℃, especially at -40℃.
● The zero-sequence output can operate continuously under a single-phase 600A current (i.e., 10 times the current).
