A Lithium niobate (LiNbO3) based integrated optical E-field sensor with an optical waveguide Mach-Zehnder interferometer (MZI) and a tapered antenna has been designed and fabricated for measurement of pulsed E-field. Experimental results demonstrate that the minimum detectable E-field of the sensor is 10 kV/m. The linear relationship between the sensor input and output is better while the input E-fields varied from 10 kV/m to 370 kV/m. Besides, from the fitting curve it can be calculated that the maximum detectable E-field of the sensor is approximately equal to 1000 kV/m.

In conditions of exceeding the maximum permissible levels of power frequency electric field, the staff must use personal protective equipment. Requirements for such means are regulated by the system of occupational safety standards. The goal of this work is analyzed new requirements for power frequency and induced personal protective equipment in the regulatory interstate standards GOST 12.4.172 and GOST 12.4.283. The personal protective equipment new requirements for various types of work are substantiated to electrical personnel health safety during the maintenance and operation of power grid facilities. Increasing requirements for personal protective equipment improves the staff protection at ground potential and at wire potential, including in emergency situations such as induced and step voltage.
