With the development of power system, more and more digital substation based on IEC61850 has been built in the world. IEC61850 is the new communication protocol which is adopted by power system so as to change the analog complicated wiring connection and protocol conversion. Based on IEC61850, all Messages, such as GOOSE, SV, MMS, PTP, etc, could be communicated on the Ethernet via fiber optical cable connection. In China, the digital substation have started since 2003, until now there are already more than 6000 digital substation put on operation, China Power Grid is planning to build 5000 more new digital substations. PONOVO, as the leading power system testing solution provider, have launched plenty of IEC61850 digital testing tools, not only digital relay test set, but also MU test set, multi-functional analyzer, 24 hours online monitoring and analyzing system, etc so that users could have suitable testing equipment for the digital substation commissioning and testings.

63800 series -
Chroma ATE Inc.
The Chroma 63800 Loads can simulate load conditions under high crest factor and varying power factors with real time compensation even when the voltage waveform is distorted. This special feature provides real world simulation capability and prevents overstressing thereby giving reliable and unbiased test results. The 63800's state of the art design uses DSP technology to simulate non-linear rectified loads with its unique RLC operation mode. This mode improves stability by detecting the impedance of the UUT and dynamically adjusting the load's control bandwidth to ensure system stability. Comprehensive measurements allow users to monitor the output performance of the UUT. Additionally, voltage & current signals can be routed to an oscilloscope through analog outputs. The instrument's GPIB/RS232 interface options provide remote control & monitor for system integration. Built-in digital outputs may also be used to control external relays for short circuit (crowbar) testing.

DP-VXI-5106 -
Data Patterns Pvt. Ltd.
DP-VXI-5106, is a 32 Channel Analog Comparator Module with 32 channels of differential analog window comparators. Each channel is provided with a window comparator as well as a Level Comparator , software selectable on an independent channel basis. All the 32 channels have been grouped into four groups of 8 channels each. This allows the user to configure the comparator module based on the application to initiate alarm action to exactly meet application requirements. Each Comparator channel can be programmed to generate a VXI bus interrupt or can be masked through software. An Interrupt is generated on an individual channel basis or on a group basis. Front panel outputs of buffered TTL and a 2-CO relay contact is available for every group (4 outputs total each). Also, a common buffered TTL interrupt output and a common 2-CO relay contact is also available at the facia providing extensive flexibility in application engineering.This module is an ideal device for GO / NO-GO testing in Test Stand Automation where important signals must be continuously monitored for system shut down purposes and safety inter-lock implementation. The hardware implementation in the Comparator module provides high-speed throughput and reliable inter-lock implementation. The interrupt out signal can be further wired as trigger signals for pre and post trigger analysis of signal data for post acquisition detailing.Each channel provides a Window Comparator implementation and a Level Comparator implementation. The configuration is programmable through software and the alarm can be generated if the signal is within the window or outside the window. Similarly, a high and low limit can be set and a trigger is generated if the signal exceeds the high limit or drops below the low limit.

DEM60C -
IBEKO Power AB
After a DC current test, such as winding resistance measurement, the magnetic core of a power or instrument transformer may be magnetized (remnant magnetism). It can cause various problems such as wrong diagnostics, inaccurate measurements on a transformer, inrush current at the start-up of a power transformer, or incorrect operation of protective relays due to magnetized CT cores. The best way to eliminate this source of potential problems is to use demagnetizer on the power or instrument transformer.The DEM60C is a fully automatic test instrument which performs three-phase transformer demagnetization. Transformer magnetic core demagnetization requires the application of AC current with magnitude decreasing to zero. DEM60C provides this AC current by internally changing the polarity of a controlled DC current. During the demagnetization process, the instrument supplies the current at decreasing magnitude for each step, following a proprietary algorithm. It can demagnetize single-phase and three-phase power transformers.The instrument can be connected to all three phases of a power transformer to be demagnetized, on either the primary or the secondary side. If a user selects specific vector diagrams for different types of transformers, DEM60C will run a specific demagnetization procedure for each transformer type (i.e., single phase, delta, wye/star, zig-zag.) without switching the test leads.DEM60C enables safe and efficient power transformer demagnetization. The instrument automatically regulates the injection of current and discharging energy from the inductance. During and after the operation, an intrinsically safe discharge circuit with an indicator rapidly dissipates the stored magnetic energy. The discharging circuit is independent of the power supply, which improves its reliability in case of loss of power.Test currents of up to 60 A DC enable efficient demagnetization of even the largest power transformers. Using a DV Win software, it is possible to control DEM60C externally.
