Product Introduction

The LDCTP-1200D Variable Frequency Transformer Tester is an instrument used to measure the performance parameters of variable frequency transformers. It meets the testing requirements for excitation characteristics (i.e., voltage-current characteristics), turns ratio, polarity, secondary winding resistance, secondary load, phase difference, and angle difference for various CT types (such as: protective, metering, and TP types). Additionally, it can be used for testing the excitation characteristics, turns ratio, polarity, and secondary winding resistance of various PT electromagnetic units.

The LDCTP-1200D Variable Frequency Transformer Tester employs advanced measurement technology for high testing accuracy; it meets various on-site testing requirements; it's easy to operate and use; compact and lightweight, making it convenient to carry.

The Variable Frequency Transformer Comprehensive Tester is widely used in power systems, grid dispatching, and electrical inspection fields, for regular inspections, maintenance, and calibration of variable frequency transformers.

Product Features

◆ Meets the excitation characteristics (i.e., voltage-current characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, phase difference, and angle difference testing requirements for various CT types (such as: protective, measuring, and TP types), and is also suitable for testing the excitation characteristics, transformation ratio, polarity, and secondary winding resistance of various PT electromagnetic units.

◆ Automatically provides parameters such as break-point voltage/current, 10%(5%) error curves, accurate limit factor (ALF), instrument safety factor (FS), second-time constant (Ts), residual magnetism coefficient (Kr), and saturated inductance.

The product meets various transformer standards including GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and automatically selects the appropriate standard for testing based on the transformer type and grade.

Based on advanced low-frequency testing principles, capable of handling CT tests with a breakpoint up to 80KV.

◆ The instrument employs the internationally popular square wave method, resulting in a more graceful excitation curve.

The instrument can store 3,000 sets of test data, and the data will not be lost in the event of a power outage.

◆ Testing is simple and convenient, with one-click completion of CT direct resistance, excitation, transformation ratio, and polarity tests. Additionally, all CT tests except for load tests are performed using the same wiring method.

◆ Easy to carry, the instrument weighs approximately 7 Kg.
