PS34 Type Three Phase Standard Power Energy MeterDetailed product description：

1、 Overview

The PS34 three-phase power meter is a new intelligent digital instrument that uses a time division multiplier and a single-chip microprocessor. It is small in size, light in weight, high in resolution, and has a high cost performance ratio. It is suitable for the calibration of single-phase, three-phase three wire, and three-phase four wire power meters and power meters with a power frequency below level 0.2. Three phase power measurement can display 100 or 150 equal parts, and power values can also be read directly according to the range. The verification results of electrical energy can be calculated according to the error formula, and the error value can be displayed within the range of+19.999% to -19.999%. The cross phase method can also be used to measure reactive power and verify reactive energy meters in three-phase systems.
This power meter includes three independent power input channels, and the voltage and current inputs of each channel are isolated by transformers. Each channel's voltage input has three commonly used voltage levels, so general meter calibration does not require an external voltage transformer. No phase sequence influence. Due to the use of specially manufactured resistors and rigorously screened reference voltage regulators, this meter has excellent temperature stability and long-term stability.
The digital processing of this power meter adopts a single-chip microprocessor. It can perform power measurement and calibration of electric energy meters. As long as the electric energy constant of the tested electric energy meter is input, it can automatically perform calculations and display errors with a high degree of automation. The operation is simple and easy to use.
