Are you a manufacturer or a trading company?

We are professional test equipment manufacturers which have our own R&D team, production workshop, quality control system and marketing depart

How long of warranty period of the products?

We offer 12 months warranty and lifelong maintenance. The warranty applies to the original purchaser that the equipment will be free of any defect in materials or workmanship for a period of one year from the date of purchase. The warranties only cover defects arising under normal use and regular service, excluding any faults and damages resulting from abuse misuse, alteration, improper installation, neglect or adverse environmental condition, not from quality problem.

How long is your delivery time?

Normally the delivery time is about 15 working days after payment. For some special customized products, it will takes 15 – 30 working days depending on technical parameter of customer requirement.

Circuit Breaker Tester KVCB-12Y - KV Hipot

General Information

General Information

Circuit Breaker Tester is a specialized instrument designed to meet the requirements for testing the action characteristics of various high-voltage switches. It can accurately measure the mechanical dynamic characteristic parameters of high-voltage circuit breakers across different voltage levels, including low-oil, high-oil, vacuum, and sulfur hexafluoride types. For circuit breakers with closing resistance, it can precisely measure the closing resistance and switching waveforms.

Features

Unique Advantage

Timing:All 12 common breakers have synchronized opening and closing times, with similar phase characteristics.
Reclosing:Each breaker’s closing-opening and opening-closing cycles are measured, including one opening time, one closing time, two opening times, short-circuit duration, and current interruption values.
Bounce:This includes the closing bounce time, number of bounces, bounce process details, and bounce waveform for each breaker, as well as the rebound amplitude during opening.
Speed:This covers the opening and closing speeds, maximum speed, and the time-travel characteristic curve.
Current:This includes the opening and closing current values and the current waveforms for the opening and closing coils.
Action Voltage:The machine provides a digital adjustable power supply (DC 30-250V/20A) for testing. It automatically performs low-voltage action tests and measures the action voltage values for each breaker.
