SUBSTATION TEST INSTRUMENTS
LRM 200
True DC Micro Ohmmeter
The LRM 200 is a microprocessor-based, true DC micro ohmmeter designed to test the contact resistance of circuit breaker contacts, switchgear, and bus bar joints. It is the instrument every test technician needs to have to maintain circuit breakers, switch gear and busbars. The LRM 200 is designed to meet the IEEE C37.09-1999, IEC62271-100 for GIS factory test and IEC62271-200 for high voltage switchboard factory test for testing circuit breaker contact resistance.
PFRS-25
Transformer Frequency Response Analyzer
The PFRS-25 can confirm the mechanical integrity of a transformer by comparing the frequency response of the transformer with the previous known results. Every transformer has a unique frequency response system which changes if the mechanical geometry of the transformer is changed. These changes can occur due to physical movement or transportation. The physical geometry can also change if the transformer experiences high fault current due to internal or external faults.
TR 100
Transformer Turns Ratio Tester
The TR 100 is a microprocessor-based single phase automatic transformer turns ratio test instrument. This field portable lightweight unit is housed in a field rugged case. The TR 100 is designed to test the turns ratio of transformers of any size per the IEEE C57.12.90 standard.
TR 300
Transformer Turns Ratio Tester
The TR 300 is a true three-phase transformer turns-ratio instrument designed to test any type of transformers. It performs turns ratio tests per the IEEE C57.12.90 measurement standard. The TR 300 generates its own three-phase excitation test voltage which is applied to the three phases of the transformer’s primary windings. The three-phase secondary voltages are measured to calculate the turns ratio.
VCBA 01
Vacuum Circuit Breaker Analyzer
The Vacuum Circuit Breaker Analyzer 01 (VCBA 01) is Power Diagnostic Instrument Company’s state-of-the-art, field portable, light weight instrument designed for the comprehensive diagnostic testing of vacuum circuit breakers. The VCBA 01 can perform high voltage DC vacuum integrity tests as well as operating time tests on the circuit breaker main contacts.
Partial Discharge Instruments
CTM-UHF System
Partial Discharge Monitoring System for Cable Terminations
Power Diagnostic Service’s CTM-UHF system offers a continuous, real-time, early warning partial discharge monitoring system for cable terminations of the HV apparatus. This system allows the user to transform their time based maintenance to condition based maintenance.
Data Acquisition Modules
On-line data acquisition system for on-line PD monitoring
PDSimply is the state of the art solution for continuous on-line monitoring of most HV/MV electrical apparatus. PDSimply’s UHF PD technology effectively separates noise from partial discharge.
PD Sensors
IPEC's UHF (Ultra High Frequency) sensors
Partial Discharge (PD) sensors are specialized devices used to detect and measure partial discharges in electrical equipment. Partial discharge is a localized dielectric breakdown of a small portion of a solid or fluid electrical insulation system under high voltage stress, which does not bridge the space between two conductors.
PDQuick
Handheld Partial Discharge Surveyor
PDQuick is designed to simplify the inspection process in substations. The fast scanning capability and multiple detecting methods allow users to quickly survey the condition of equipment, and determine if detailed investigation is required. The handheld device is equipped with dual detection channel and powerful auto-analysis function to determine PD type.
TMS-UHF System
Comprehensive Transformer PD Monitoring System
Power Diagnostic Service’s TMS-UHF system offers a continuous, real-time, early warning partial discharge monitoring system for HV/MV power transformers. This system can transform time-based maintenance to condition-based maintenance. Advances in digital technology now make it possible to detect the presence of partial discharge (PD) in a transformer effectively.
