The ClearTest is a completely new design that briefly energizes the transformer and takes a snapshot of the transformer condition by measuring the voltage, current and power factor of the test signal. The ClearTest finds transformer defects that include:
-
A single shorted turn in the primary orsecondary side of a transformer
-
Open coils or blown internal fuses or breakers
-
Partial shorts including shorted turns, shorted turn layers, coil to core shorts and primary to secondary shorts
-
Bad transformer ratios resulting from shorted turns
ClearTest looks both inside and outside the transformer - testing the coil, core, and winding as well as between the transformer and whatever it is connected to.
CLEARTEST® TRANSFORMER TESTER
The ClearTest can test new or reworked, single or three phase transformers and all the connections made to them, up to and including the revenue meter.
-
Use it in the field to test the primary and secondary sides of transformer installations for short circuits prior to energizing.
-
In the shop, use it for quick screening of incoming and outgoing transformers for primary and secondary shorts or opens, including internal fuses and breakers.

A magnet is included to hold the ClearTest in place while testing
HD Electric CT-300 ClearTest变压器测试仪
ClearTest 是一种全新的设计，可通过测量测试信号的电压、电流和功率因数，为变压器短暂通电并获取变压器状况的快照。 ClearTest 可发现变压器缺陷，包括：
变压器初级或次级侧的单匝短路
线圈开路或内部熔断器或断路器熔断
部分短路包括短路匝、短路匝层、线圈到磁芯短路和初级到次级短路
匝间短路导致变压器变比不良
ClearTest 查看变压器的内部和外部 - 测试线圈、磁芯和绕组以及变压器与其连接的任何设备之间。
CLEARTEST® 变压器测试仪
ClearTest 可以测试新的或返工的、单相或三相变压器以及与它们建立的所有连接，包括计费表。
在现场使用它在通电之前测试变压器装置的初级和次级侧是否短路。
在商店中，使用它来快速筛选进出变压器的初级和次级短路或开路，包括内部熔断器和断路器。
特征
