Product Introduction

The Transformer Dielectric Loss Tangent Delta Tester is an instrument specially designed for testing the capacity of standard distribution power transformers under low voltage and small current. Its main components include an LCD display, fuse box, grounding post, terminal block, etc. The Transformer Dielectric Loss Tangent Delta Tester is small in size and light in weight, with an integrated design that makes it easy to carry and operate in the field.

Features

HZ-2000H Transformer Dielectric Loss Tangent Delta Tester is sold well in the world market and worth recommendation for its excellent quality and reasonable price. Our tester can accurately measure the capacity of various distribution transformers with passive measurement, which is convenient and accurate. In addition, it comes with its own internal power supply and automatically generates three-phase high-power test power, which can measure no-load current, no-load loss, short-circuit voltage and short-circuit loss of various types of transformers.

Measurement Method and Principle

According to whether the tested product is grounded or not, there are two kinds of measurement methods, namely, the forward connection measurement method and the reverse connection measurement method. The principles of the two measurement methods are shown in figure 1:

At the 10kV side of the high-voltage power supply, the high-voltage power supply is divided into two channels, and the first channel feeds the standard capacitor CN inside the machine. The dielectric loss of this capacitor is very small, which can be considered as zero, i.e. pure capacitive current. This current ICN can be used as the capacitive current reference. On the Cx test side, the test current Icx is collected into the machine through the sampling resistance R. The Icx can be decomposed into horizontal and vertical components, as shown in figure 2. tgδ value can be obtained by calculating the ratio of the horizontal and vertical components.

In FIG. 1 (a), Cx is the ungrounded sample, and the sample current Icx enters the sampling resistance R from the sample end to obtain the full current value. In FIG. 1 (b), Cx is the grounding sample, the Cx end of the machine is directly grounded, and the current Icx obtains the full current value from the high-voltage end of the sample to the sampling resistance of the machine.

We will comprehensively increase the pace of corporate internal restructuring, improve product innovation technology to create High-Efficiency Wh Series Double Screw Conical Mixer that meet customer needs. Our employees have undergone long-term technical training and are professional technical consultants to ensure that a reasonable, efficient, energy-saving and economical plan is designed for customers. We look forward to your visit and cooperation!
