type of high pressure jer phase detectors     Power system check phase is a regular work. The traditional fixed phase method adopts high voltage PT or high-pressure check appliances， the former equipment cumbersome and high-voltage lead down to PT very insecure， which depends on is faint glow instructions， easy to cause the mistakenly judgment. My company launched HREC - 1 type of high pressure jer phase detectors， weigh only high-pressure PT weight of 1/20， easy to carry， safe and reliable operation， instructions， be clear at a glance， and is the necessary instruments high-pressure electrician. HREC - 1 type series high-voltage fixed phase detectors (also called: school phase detectors， nuclear phase estimator) Instrument measurement range:0.22kV，0.38kV，1kV~10kV~1000kV.     type of high pressure jer phase detectors     Power system check phase is a regular work.
