The Bierer PD800W Cordless Phasing Tester accurately and easily operates in multiple applications including:
A unique tester, the Bierer PD800W is an all-in-one kit for three-phase secondary systems, capacitive test points, URD systems and overhead and transmission/substation systems. The tester operates like a conventional phasing tester, but does not require an interconnecting cable or extension resistors.
With each probe being water resistant, and sturdily constructed, the PD800W is designed to withstand wear-and-tear, and is completely shielded to minimize stray field interference.
