YCPQA-9901 Power Quality Analyzer is used to long-term or short-term on-line monitor voltage, current and power of the power grids, providing reliable monitoring data for making harmonic pollution reduction approaches for the power grid. 

When testing three-phase energy meters where the voltage and current measurement circuits cannot be separated (closed links), it is necessary to isolate the voltage and current circuits. In multi-meter inspection, due to the complexity of three-phase circuits, the voltage isolation method can no longer meet the needs of actual inspection, and current isolation method is needed to ensure the inspection accuracy.

• The LPEP 270/20G T3 Series Surge Protective Device is primarily designed for DC power supply protection in secondary power systems, including distribution cabinets, feeder panels, control/monitoring panels, and UPS cabinets.

The LPEP385-3/R/SMA-4 Combined Lightning Protection Junction Box is primarily designed for joint wiring and surge overvoltage protection in power transformer load metering terminals, energy collection terminal boxes, and smart energy acquisition terminals.

• The LPEP 385/20M T2 Series Surge Protective Device is designed for overvoltage/surge protection in power secondary systems, including distribution cabinets, feeder panels, control/monitoring panels, UPS cabinets.
