WECO's next generation Portable Tester/Analyzer allows you to implement three-phase field-testing, using a Radian Research™ RD-30 internal standard complimented by a sophisticated, lightweight package. The WE-20 allows you to execute a multitude of tests at the customer's site. You can test the meter with the customer's load, perform CT burden and ratio tests, and verify system wiring to give you the peace-of-mind that the entire metering installation is correct.
The DTR® Model 8510 is a portable digital transformer ratiometer designed for on-site testing of power, potential and current transformers. When connected to a non-energized transformer, the DTR® Model 8510 accurately measures primary to secondary turns ratio, while simultaneously displaying polarity and excitation current. The DTR® is fully automatic and uses an ANSI/IEEE compliant test method.

HTCT-201 CT ratio tester can test the HV primary current, LV secondary circuit of the HV measuring equipments (35 KV or less than 35 KV system) without disassembling the wire or power off, and calculate the ratio.
This primary current injection testing system is designed to perform primary tests requested in substations commissioning. It allows to perform different tests and measurements on current transformers, voltage transformers, power transformers, protection relays, energy meters and transducers.
The CT/PT Ratio Tester is designed to carry out routine accuracy and linearity tests on the LIF CT, isolating CT and single phase voltage measuring transformer used in control cubicles of traction and auxiliary converter. The system consists of a variable voltage, programmable sine wave generator with very low harmonic distortion for generating an excitation signal for the CT/PT under test.
GDVA-403 CT analyzer is special tester for current transformer. It takes IPC as core to sample and data process. The instrument finishes CT tests based on different low frequency. It has 8.4 inches LCD to display and a 8.4 inches touch pad for operation. The tester has the characteristic of high precision, strong anti-jamming and easy operation.
Fully automatically tests CT and PT, with auto test range with accuracy upto 0.02%With electronic Current & voltage load box, can set output power and power factor at random.Adopts 10kVA computer controlled linear power source, so solves inaccurate orientation problem of S-class CT test, meanwhile can test error of CT at 200%.
The innovative design allows utilities to fully test a metering installation with one piece of equipment. Customer load meter testing, phantom load meter testing, CT burden and ratio testing along with de-magnetization can be performed with one solution. In addition, vector diagrams, voltage and current waveforms, and harmonics data up to the 100th harmonic can all be analyzed to complete a true wiring verification.
