Checking phase power system is a regular task. PT,,PT,,. Conventional fixed-phase method using high pressure or high pressure electroscope PT, the former equipment, heavy, high-voltage quoted down to the PT is very safe, which rely on the faint glow instructions easily lead to mistaken judgments.

Our company introduced HREC-1-type high pressure phase detector, the weight of high-voltage PT is only the weight of 1 / 20, easy to carry, safe and reliable, clear instructions, is essential for high-voltage electrical apparatus.
HREC-1(:,) HREC-1 series High Pressure phase detector (also known as: School phase detector, the nuclear phase detector)
