Automatic Three Phase Inductance Capacitance Meter For Measuring Compensation Capacitor

Automatic Three Phase Inductance Capacitance Meter For Measuring Compensation Capacitor

1. Product Name:

Automatic three phase inductance capacitance tester

2. Equipment Description:

Automatic inductance capacitance tester is specially developed for problems existing in substation field measurement of capacitance value of capacitor, it solved the following problems:

(1) Field measurement capacitor needs dismantling cables, not only the big workload but also easy to damage the capacitor.

(2) Low capacitance meter output voltage causes the fault detection rate is low.

The instrument has characteristics of small measured workload, fast and simple, stable performance, high measurement accuracy, high fault detection, etc.

(3) Reactor inductance measurement.
